Schizophrenia is a chronic disease that requires lifelong medical care and supervision. There is a high rate of relapse, mostly caused by poor adherence to oral antipsychotics. Long-acting injectable (LAI) antipsychotics have proved effective in schizophrenia and other severe psychotic disorders due to the stable blood levels, leading to a reduction of the risk of relapse. LAIs are associated with better functioning, quality of life, and patient satisfaction. In Treatment-resistant schizophrenia the combination of antipsychotics is a common practice. Nevertheless, the combination of two different long-acting injectable antipsychotics is not frequent.

A case of a 34-year-old man is presented, previously diagnosed of Schizophrenia, with highly disabling chronic positive symptoms. With no in-sight and no will in receiving treatment. Has been stable for a year while being in treatment with paliperidone 525mg LAI/ 10 weeks, and aripiprazole 400mg LAI/28 days.

The patient was closely observed and given oral paliperidone, after 5 days long-acting paliperidone was introduced. He was discharged with mild improvement of his psychiatric symptoms. While being in treatment with Paliperidone 525mg, he kept vivid delusions and hallucinations. The patient still refused to take any oral medications. Long-acting aripiprazole 300mg was added to the treatment.

He showed clinical improvement after a month. He has been stabilized for one year.

Treating resistant schizophrenia is among the most challenging clinical endeavors. A very helpful approach to improve adherence in schizophrenia is the use of long-acting injectable (LAI) antipsychotics. A major effort on scientific research of combination of LAI is needed.

Clozapine use is not deprived of serious complications that can condition treatment strategies, particularly hematological. Recognizing the time it takes for these effects to set, can therefore help to better screen their appearance, improving healthcare.

To study the time of onset of hematological adverse reactions in patients treated with Clozapine.

A longitudinal, retrospective and descriptive study on a period of 20 years starting from the first of January 2000, at the psychiatry department A of the Razi hospital in Tunisia. This study was conducted on patients treated by Clozapine. The data was collected from patients’ medical files using a pre-established sheet.

The studied sample included 64 patient. Hematological disorders were found in 21 patients (32.8%). The mean time of onset of hematological adverse reactions was 119.71±126.56 days. Indeed, some patients had presented more than one hematological disorder and this at different times. Mild to moderate neutropenia had a mean time of onset of 502.57±908.32 days. The time of onset of eosinophilia was 937.75±1725.87 days, 297.67 ± 444.93 days for thrombocytopenia, 741±1268.85 days for leukopenia, 69.25 ± 48.19 days for hyperleukocytosis and 183. 33±231.80 days for anemia. Two cases of agranulocytosis were noted: one case occurred 10 years and three months from treatment beginning and the second case occurred after 7 months of treatment onset.

The time of onset of hematological side effects with clozapine varies widely and cannot be predicted with precision. Early, more frequent and regular surveillance is therefore necessary in this population.

41 years-old man diagnosed of schizophrenia and peripheral spondyloarthropathy HLA-B27 (-) in treatment with methotrexate. Psychiatric background: First psychotic episode at 18, with no further medical monitoring. In 2018 he underwent a new episode consisting in auditory hallucinations, delusional ideas and clinophilia of months of evolution. He was sent to a Psychiatric Rehabilitation Unit and prescribed aripiprazole 20mg. The routine blood analysis revealed triglycerides level of 414mg/dL, with previous normal levels (123 mg/dL), without no other cause to justify it.

To study the relationship between aripiprazole treatment and acute hypertriglyceridemia.

A clinical case is presented and available bibliography about the relation between aripiprazole and acute hypertriglyceridemia is reviewed.

Hypertriglyceridemia was confirmed in the second analysis, so we concluded it was due to the start of aripiprazole, after rejecting other potential causes. Aripiprazole was replaced by cariprazine 3mg because of its similar profile. The analysis was repeated after a month and the normalization of the triglyceridemia (159mg/dL) was verified, while cholesterol levels remain stable. Moreover, the patient experienced an improvement in akathisia and sedation.

Although metabolic impact is not expected with aripiprazole, after reviewing the bibliography we have found a clinical trial and a case series that described this adverse effect. Our case highlights the importance of closely monitoring of patients in whom an antipsychotic treatment is started due to the high mortality and morbidity related to cardiovascular diseases.

Serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants thanks to the overall safety and tolerability spectrum. However, they can cause different side effects that not all of them are well identified.

We intend to clarify the clinical presentation of mydriasis caused by Escitalopram.

Reporting the case of a patient suffering a major depressive disorder, that presented a mydriasis after adjusting her antidepressant medication. Then, we conducted a literature review using “PubMed” database and keywords “Mydriasis”, “escitalopram”, “SSRI”,” side effects”.

A 29-year-old female with no past clinical history, presented in May 2021 a severe depression requiring an antidepressant treatment. Under 10 mg per day of escitalopram there was a partial remission of the symptoms, leading to increase the dose by another 10 mg. One month after taking 20 mg/day, she consults before the appointment suffering from a blurry vision and photophobia. Ophthalmologic examination showed a bilateral reactive half-mydriasis, eye pressure was 14 mmHg and fundus examination was normal. Iatrogenic origin of mydriasis was suspected. A gradual interruption of the medication lead to disappearance of the latter. A pharmacological investigation concluded to the suspension of escitalopram and to be vigilant if antidepressant medication would be needed.

Mydriasis is an uncommon side effect caused by SSRI that needs to be kept in mind by clinicians. Therapeutic patient education can help to detect abnormal side effects and treat them if needed.

Esketamine is an S-enantiomer of ketamine approved by the EMA for treatment-resistant depression (TRD). As an NMDA receptor antagonist, its administration results in increase of glutamate release and AMPA receptor activation, supporting both rapid-onset and long-term antidepressant effects. Short-term tolerability seems acceptable but major concerns remain regarding long-term safety, specifically regarding potential neurocognitive toxicity.

To clarify the potential short and long-term cognitive beneficial-effects and side-effects of esketamine.

Research was made using the Medline database, through the Pubmed search engine, using the keywords: “esketamine”, “cognition”. Only randomized-controlled trials were considered.

One study focused on the effects of intranasal esketamine (INE) on cognitive functioning in 24 healthy individuals, who were evaluated pre- and postdose (40 min, 2h, 4h and 6h). The results showed a decline in cognitive performance at 40 min postdose, returning to comparable levels as placebo by 2h postdose. Another study, with a follow-up of 1 year, involving 802 TRD patients, accessed the long-term safety of INE. In patients aged <65 years-old, performance on all cognitive tests remained stable or slightly improved from baseline during long-term treatment. In patients ≥ 65 years-old, the mean performance on all tests improved or remained stable, while the simple and choice reaction time began slowing at week 20.

Esketamine has proven to be a promising new option for the treatment of TRD and available studies have shown promising results regarding patients’ cognitive function. Larger clinical trials are needed to further evaluate its short-term and long-term cognitive effects.

Schizophrenia spectrum disorders may severely limit ability to achieve and maintain gainful employment of affected working-age individuals.

Assess the employment status in patients with schizophrenia spectrum disorders treated with long acting injectable paliperidone palmitate after the switch from oral antipsychotics.

A single centre mirror image design study of 115 patients with schizophrenia spectrum disorder was conducted in a tertiary level psychiatric hospital. Data were collected for period of 12 months prior toand 12 months after switching from oral antipsychotic to long acting injectable paliperidone.Employment status for 6 enrolled patients was missing.

Mean age of enrolled patients was 38,4±11,6 years. Of the 109 patients analyzed for employment status, 44,4% remained employed for 12 months after switching to long acting injectable paliperidone while 4,6% patients changed their employment status from unemployed to employed after the switch. No patient changed their employment status from employed to unemployed after the switch. 9,2% patients were already retired at the beginning of study period and 5,5% of patients maintained their student status. 36,7% patients remained unemployed for the whole study period. The correlation between employment status of employed and unemployed patients and duration of illness was borderline significant with p=0,049.

The data from this study suggest that use of long acting injectable paliperidone contributed to preservation of working ability of working-age patients suffering from schizophrenia spectrum disorders.

Valproic acid is a psychotropic drug used for several years, due to its properties as a mood stabilizer, being considered as first-line treatment for bipolar disorder. In addition to its teratogenic potential, which prevents its recommendation for the treatment of bipolar disorder in women of childbearing age, valproic acid is associated with some side effects, such as gastrointestinal symptoms, alopecia, weight gain, tremor or hepatotoxicity. Hyperammonemia is a side effect that is little described, but relatively frequent, and may progress to variable encephalopathy.

The authors describe a clinical case of a 48-year-old female patient, hospitalized due to a manic episode, who was prescribed valproic acid, in association with lorazepam and olanzapine.

After three days on a dose of 1000mg of valproic acid, the patient began an acute condition of confusion, psychomotor retardation, temporal-spatial disorientation and ataxia. Infection, electrolyte disturbance and acute cerebral event were excluded. Noteworthy only hyperammonemia. Valproic acid was withdrawn and replaced by lithium, with the patient recovering from the confusional state two days later.

Hyperamonemic encephalopathy secondary to valproic acid was concluded. The mechanisms of valproic acid-linked hyperammonemia are not clear, although it appears to be independent of hepatotoxicity. The most studied hypotheses are related to glutamine reabsorption and serum levels carnitine in patients medicated with valproic acid.

It is essential that there is a high level of suspicion in clinicians for this secondary effect of valproic acid, in order to adequately treat the patient who presents with acute confusional conditions, not explained by other complications.

We present the case of a 54-year-old man diagnosed with mixed histrionic / obssesive personality disorder admitted in a long-stay hospital. Symptoms began at 40 years of age, predominantly anxiety and agoraphobia alongside somatic complaints. During his admission, the symptoms markedly fluctuated. The patient alternated periods in which he presented confusion with others of irritability, disinhibition, and stereotyped movements. Moreover the patient spent long periods of time in bed with little or no communication with other patients or staff.

The different pharmacological approaches which were carried out and their consequences are analyzed.

It is a common practice to increase the number of prescribed drugs or their doses when symptoms worsen. The result is polymedication and higher doses above maximum levels in the technical sheet. Reducing medication is rarely considered as a strategy.

A case report is presented alongside a review of the relevant literature regarding different long-term pharmacological treatments and their side effects.

The suspension of the antipsychotic treatment which had been administered for years represented a significant improvement. Withdrawal of Olanzapine resulted in a significant improvement.

It is important to review the prescription of each medication in time, as well as to consider their possible side effects.

Nowadays, relapses are typical in patients with schizophrenia and may have serious implications due to most of them are caused by a lack of adherence to treatment.Therefore, numerous long-acting injectable antipsychotics (LAI) have been developed as aripiprazole depot who need a proper oral supplementation. Since November 2020, FDA approved a new treatment indication with a double injection start and a single dose of 20mg of oral aripiprazole, with the aim of avoiding oral supplementation during the next 14 days.

The purpose of our study is to expose our experience with the new double injection start with aripiprazole LAI, regarding the rehospitalization rate.

A prospective study (n=17 patients) has been developed between November 2020 and October 2021 with the purpose of studying the rehospitalization and antipsychotic adherence after the new guideline of aripiprazole

After an 11-month-follow-up, it is noticed a 65% non-rehospitalization rate and a 76% proper treatment persistence rate. The 94% did not present any kind of side effects, only one patient had a case report of bullous pemphigoid. Regarding the concomitant use of other antipsychotics, 82% of the patients remained in monotherapia. The average stay time was shortened (11 days) regarding the standard dose (14 days).

The new LAI regimen is well tolerated in our patients obtaining a high treatment persistence after several months of hospital discharge. It was already possible to shorten the time of rehospitalization, not having to add oral aripiprazole for 14 days. Most patients were discharged are on antipsychotic monotherapy and have not been rehospitalized in the short term.

Approximately 30% of individuals diagnosed with schizophrenia suffer from treatment-resistant or refractory schizophrenia. The gold standard for treatment is clozapine. However, a significant number of patients discontinue clozapine treatment and this carries a poor prognosis.

This study explores patients’ motives for cessation of clozapine therapy and its prevalence.

A longitudinal, retrospective and descriptive study on a period of 20 years, at the psychiatry department A of the Razi hospital in Tunisia. Data was collected from the medical files of patients trated by clozapine using a pre-established sheet.

The studied sample included 64 patient records. Treatment with clozapine was stopped spontaneously or following a medical decision in 37 patients (57.8%). The total number of clozapine stops in these 37 patients was 70. Indeed, each one of these patients had stopped treatment at least once. Clozapine was discontinued by some patients in the study sample for poor compliance(45.9%), for adverse side effects of treatment (16.2%) and by treating physicians for poor response treatment (8.1%). Clozapine was discontinued by 11 patients for hematological adverse reactions, representing 27.9% of the total number of clozapine discontinuations. Withdrawal of clozapine was indicated in 2 cases of agranulocytosis(18.2%), in 2 cases of moderate neutropenia(18.2%), in 3 cases of eosinophilia (27.2%), in 3 cases of thrombocytopenia (27.2%) and in 1 case of severe anemia (9.2%).

Clozapine discontinuation was essentially caused by poor patients’ observation and hematological adverse reactions appearance.Future research should seek to further investigate clozapine cessation factors in order to better benefit from the medical virtues of this molecule.

Drug-induced liver injury is one of the leading causes for acute liver failure and drug withdrawal after marketing approval. One important risk factor is the extent of exposure of the hepatocytes to a substance, either by high doses or by long-term medication. In many psychiatric diseases, like schizophrenia long-term use of drugs is common. However, systematic data on the hepatotoxic potential of antipsychotics is scarce.

To perform an explorative analysis of pharmacovigilance data on the risk of hepatotoxicity related to the use of antipsychotics.

We conducted an explorative case/non-case study based on data from VigiBase for 30 antipsychotics marketed in the European Union. Reporting odds ratios were calculated for antipsychotics associated with the SMQ “Drug related hepatic disorders - comprehensive search” and the SMQ “Drug related hepatic disorders - severe events only”.

We found several associations of antipsychotics with drug-induced liver injury including associations with severe events. 17/30 antipsychotics were associated with “Drug related hepatic disorders - comprehensive search”, and for 10/30 substances were associated with severe hepatic events.

Several antipsychotics are associated with the risk for hepatotoxic side effects, even severe ones. Further research is warranted on patient and substance-dependent risk factors.

Paliperidone palmitate 1-month (PP1M) is a Long-acting injectable antipsychotic formulation, approved for the treatment of schizophrenia and schizoaffective disorder. Recently, paliperidone palmitate 3-months (PP3M) formulation was introduced, which maintains stability while offering a longer dosing interval for the maintenance treatment in patients previously treated with PP1M. Despite of this, many patients are treated with PP1M without transition to PP3M.

To identify variables explaining maintenance of PP1M treatment instead of going to PP3M. We hypothesize that more severe patients are delayed in transition to PP3M because of expectation to complete stabilization.

A descriptive analysis of 123 patients, diagnosed with psychotic disorders, on treatment with paliperidone palmitate 1 month or 3 months, was performed. Age, sex, type of paliperidone treatment, hospitalizations after the initiaton of treatment, years since diagnosis, polytherapy and toxic habits were some of the variables measured and compared between both groups (PP1M and PP3M).

Most of patients (63,41%) were on PP3M. Both groups shared characteristics like male sex predominance, schizophrenia as the most common diagnosis, having a recent onset diagnosis, same frequency of polypharmacy and same pattern of drug consumption. There was a slight difference between both groups regarding severity. PP1M and PP3M showed respectively 33% and 16,7% of admissions after initiation.

No clear pattern determines less transition to PP3M from PP1M. No statistical difference was found except form the difference found in admission after change of treatment (to PP1M or PP3M), which could reflect influence of severity in treatment. Future research is needed in order to better elucidate this association.

Many psychotropic drugs can induce weight gain with differences in their metabolic risk profiles (i.e. high, medium or low-risk).

To compare the weight evolution of patients switching versus patients keeping their psychotropic drugs with different risk-profiles.

Data for patients switching or keeping the same drug were obtained from the Psyclin (from 2007 to 2015) and Psymetab (2007- 2019) cohort studies, conducted at the Lausanne University Hospital, Switzerland. Patients either switched from a high to a low-risk, a high to a medium-risk, a medium to a low-risk drug, or for a drug with the same risk category. Patients not switching either kept a high, medium or low-risk drug. The evolution of weight is currently being analyzed using a linear mixed-effect model.

Preliminary results showed that switching from a high to low-risk molecule had the strongest impact on weight changes. The analysis being ongoing, the quantitative results will be presented at the congress.

Switching from a high-risk to a low-risk molecule is likely to have the strongest impact on weight changes.

Clozapine is one of the most effective antipsychotic drugs. On the other hand, it can cause serious side effects which have to be monitored. An adverse effect is myocarditis, a type B Clozapine reaction that can be fatal if it is not early diagnosed.

To report a case of a patient with Clozapine induced myocarditis.

A 48 years old women with a schizoaffective disorder was admitted to our Hospital due to a clinical decompensation. She had a manic episode with psychotic symptoms (persecutory delusions and auditive hallucinations). Clozapine was introduced after there were no improvement with Olanzapine, Risperidone and Valproic Acid. A dose increase was made reaching 100 mg/day the first week and 200 mg/day the second week. The third week she started with a 39ºC fever, decreased oxygen saturation, leukocytosis (9560 103/mm3), elevated PCR (210 mg/l) and elevated troponins (52,88 ng/l). EKG and other medical tests did not show alterations. There was not found a clear etiology, so Clozapine was retired as a cautionary measure. The differential diagnosis for etiology included viral infections, Clozapine induced myocarditis or idiopathic.

A few days after the withdrawal of Clozapine, cardiac symptoms improved, suggesting it was the most probable etiology.

Although it is not very likely to occur, it is important to consider myocarditis as a sever Clozapine side effect.

Valproic acid (VPA) is considered a well-tolerated antiepileptic drug used in Bipolar Disorder as a mood stabilizer. Nevertheless, VPA has been related to several adverse effects. Neutropenia is included as a potential adverse effect, although in clinical practice it is not often measured with regularity.

To report a case of a patient with Bipolar Disorder type 2 and Personality Disorder Cluster B treated with VPA with a neutropenia caused by VPA.

A 61-year-old woman assists to the outpatient psychiatric unit in order to a pharmacological treatment adjustment. A blood test is performed showing a decrease in the levels of neutrophiles in comparison with previous tests. Psychiatric history is revised finding and association between the prescription of VPA and the reduction of neutrophile levels. When this drug was removed, neutrophile levels had increased again up to normal levels.

Due to the relationship between neutropenia and VPA treatment, we decided to discontinue this drug. At the beginning the patient doesn’t agree with the withdrawal of VPA treatment due to its effectiveness in her mood stabilization. Psychoeducation sessions are performed in order to explain risk and benefits of potentials treatment alternatives versus maintaining the same prescription. Finally the patient accepts the switch of the mood stabilizer treatment to oxcarbazepine with a good tolerability and effectiveness.

Periodical blood test monitoring is needed in order to study adverse effects as neutropenia in patients with VPA treatment.

Levetirazetam is an antiepileptic drug with psychiatric adverse reactions. It includes psychosis, paranoia or hallucinations. The frequency is less than 1%.

To describe a case of Psychosis produced by Levetirazetam

Retrospective review of clinical records and complementary test, including psychiatry, electrophysiology and neurology. Diagnosis schales such as Salamanca Questionnaire were used as suport.

A 42-year-old woman diagnosed with tuberous sclerosis and undergoing treatment with levetirazetam acudes to the emergency department for behavioral disorders. She has presented an episode of aggression against a relative threatening him with a kitchen knife. The family reports that since the change in antiepilepticus 1 month ago, the patient has presented strange behaviors. Te Patient is conscious, uncooperative. Barely Approachable. Suspicious of her surroundings, with psychomotor restlessness, self-reference ideas and sparse speech. Auditory hallucinations seem to be present, as well as depressed and irritable mood. Psychic and somatic anxiety is found.

Levetirazetam is discontinued, being replaced by valproic acid. Risperidone is started at a 3 mg dose. Treatment is well tolerated, and clinical stability is achived. Cluster A personality traits are found. Complementary test Blood and Urine simples, Imaging tests (CT and MRI), electroencephalogram and Electrocardiogram show no alterations

Levetirazetam can cause psychiatric adverse effects. it is important to make a proper diagnosis before a first psychotic outbreak in later life. Drugs that can produce psychiatric side effects should be identified and patients should be inform.

We present the case of a male patient, 47 years old, diagnosed with schizophrenia, that was admitted at our hospital presenting a confusional state, with agitation, motor discoordination and difficulty breathing. At the blood analyses there was evidence of an increase in cardiac enzymes. The clinical manifestations had begun 5 days before, with slight leucocytosis showing in a routine blood test made after initiating clozapine, followed by fever, vomiting and progressive impairment of general clinical state.

To describe a case of clozapine-induced myocarditis, which is a known, but rare, side effect of clozapine and to do a brief review of the existing knowledge on this matter.

The authors undertook an article review using PubMed database and a thorough analysis of the clinical case.

The hypothesis of clozapine-induced myocarditis was the main diagnosis considered since the beginning, nevertheless, a thorough clinical examination and complementary tests were made and all the previous psychopharmacological treatment was suspended. The final diagnosis was based on the clinical presentation (fever, vomiting, shortness of breath, confusion and impairment of general state), the elevation of CRP, PCT and TnI and findings on echocardiogram that suggested myocarditis (moderate systolic dysfunction of the left ventricle due to global hypokinesia and a non dilated left ventricle).

The clinical manifestations observed, the results of the complementary diagnostic tests and the review of the existing literature, allowed to make the diagnosis of clozapine-induced myocarditis. We find of considerable importance to continue to publish and study this matter as it is still insufficiently known.

Interpersonal distance regulation is an essential element of social communication. Its impairment in autism spectrum disorder (ASD) is widely acknowledged among practitioners, but only a handful of studies reported empirical research. However, these studies did not measure the alterations of vegetative functions related to interpersonal distance.

We introduced a new experimental design to systematically measure interpersonal distance along with heart rate variability (HRV) in adults with ASD and tested the modulatory effect of intentionality, eye contact, moving activity, and attribution.

Twenty-two adults diagnosed with ASD and 21 matched neurotypical controls participated in our study from 2019 October to 2020 February. Our new experimental design combined the modified version of the stop distance paradigm with HRV measurement controlling for eye contact between the experimenter and the participant to measure interpersonal distance in incidental and intentional conditions.

Our results showed greater preferred distance in ASD in the intentional (W=103, p=0.002) but not in the incidental condition. These results were altered with eye contact and the participant’s role (active vs. passive) in the stop distance task (F(1,41)=6.150, p=0.017). Moreover, we found lower baseline HRV (t=-2.060, p=0.023) and reduced HRV reactivity in ASD; however, these vegetative measurements could not predict preferred interpersonal distance.

Our study highlights the importance of interpersonal distance regulation in ASD and the need for comprehensive experimental designs to grasp the complexity and underlying factors of distance regulation in typical and atypical populations.

Endorphins have been associated with analgesia and pleasurable activities. However, the so-called “happy chemicals” are far more complex than initially thought. Research shows that their impact on human behavior is modulatory, with the main goal not being “happiness” but a “return to the most desirable state” – which can be highly context-dependent.

Review of the modulatory functions of endorphins on human behavior and their possible implications in psychiatric conditions.

Pubmed search consisting of the MeSH terms “Endorphins”, “Opioid Peptides”, “Behavior”, and “Psychiatry”.

Endorphins elicit pleasure via stimulation of the release of dopamine from the ventral tegmental area to the nucleus accumbens. They are known to be involved in analgesia and stress response and social interaction. Endorphins can be released in a multitude of circumstances that may seem contradictory – having both inhibitory and stimulating roles in appetite, sexual response, and memory– but are modulatory effects depending on what constitutes homeostasis in each context. Peripheral levels of endorphins have been found low in depression and post-traumatic stress disorder. In schizophrenia, studies suggest that peripheral levels are high during psychosis, low in chronic disease and that naltrexone seems to improve auditory hallucinations. Endorphins may also have a role as markers of treatment response.

Endorphins have a complex role in behavior and homeostasis. These molecules could have implications in psychiatry- given that they are part of our stress response and are released to promote a more “desirable state”. Their role as a marker of illness or response to treatment needs further investigation.

Individuals with severe mental illnesses (SMI) often present the knowledge about a task but in real-time do not perform it fully, or not as efficient as planned. This performance gap may be explained by difficulties with Executive Functions (EF).

The aim of the presentation is to describe how people with and without SMI experience and perform grocery task. This, with considering this path from several directions including the subjects’ point of view using eye-tracking device during task performance.

Forty-three individuals had answered questions in regards to their shopping habits and performed the Test of Grocery Shopping Skills (TOGSS). The actual performance was accompanied by wearing an eye-tracking device which recorded the behavior and eye movement. We hypothesized that significant differences will be found between people with SMI and controls both in the routine grocery habits and in observed performance.

No significant differences in age or gender. The groups differed significantly only in education, with the SMI group having fewer years of education. As a weekly routine, SMI subjects perform less frequent shopping (40%) than control group subjects (67%). TOGSS sub-outcomes indicated performance efficiency (time and redundancy) were significantly higher in the research group than in the matched control group (p <.01), with the SMI group spending a longer time performing the task and entering more aisles than required – redundancy.

These preliminary findings indicate that individuals with SMI spend more time dwelling while selecting ingredients. Besides the path in the supermarket, it might explain their performance in other everyday activities.
