Low-intensity psychological interventions are effective for children and young people (CYP) with mental health difficulties and can help bridge the demand–capacity gap. Despite increasing awareness, training and use of low-intensity psychological interventions, it is not yet understood what is being implemented in clinical practice in the UK and the associated evidence base.

This paper presents two studies; first, a national survey (n=102) of practitioners to identify low-intensity psychological interventions currently delivered in practice and second, an exploration of the availability and the strength of empirical support (characterised as ‘gold’, ‘silver’ and ‘bronze’) of low-intensity CBT interventions for CYP.

The first study found a wide variety of interventions being used across different services; 101/102 respondents reported using routine outcome measures. The second study identified 44 different low-intensity interventions, 28 of which were rated as having gold empirical support. However, only 13 of the gold interventions were considered accessible for practitioners and only two were reported being used in routine practice.

These findings highlight that these interventions have been developed and empirically tested, but many are not easily accessible, highlighting the ‘research–practice’ gap in the provision of low-intensity interventions. There is a need for an increase in standardisation of care and accessibility of gold interventions. This paper hopes to begin the process of creating a hub of low-intensity interventions that are accessible and empirically supported to improve equity of access and outcomes of low-intensity psychological interventions for CYP.

Although effective treatments for bulimic-spectrum eating disorders exist, access is often delayed because of limited therapist availability and lengthy waiting lists. Web-based self-help interventions have the potential to bridge waiting times for face-to-face treatment and overcome existing treatment gaps.

This study aims to assess the effectiveness of a web-based guided self-help intervention (everyBody Plus) for patients with bulimia nervosa, binge eating disorder and other specified feeding and eating disorders who are waiting for out-patient treatment.

A randomised controlled trial was conducted in Germany and the UK. A total of 343 patients were randomly assigned to the intervention ‘everyBody Plus’ or a waitlist control condition. The primary outcome was the number of weeks after randomisation until a patient achieved a clinically relevant improvement in core symptoms for the first time. Secondary outcomes included eating disorder attitudes and behaviours, and general psychopathology.

At 6- and 12-month follow-up, the probability of being abstinent from core symptoms was significantly larger for the intervention group compared with the control group (hazard ratio: 1.997, 95% CI 1.09–3.65; P = 0.0249). The intervention group also showed larger improvements in eating disorder attitudes and behaviours, general psychopathology, anxiety, depression and quality of life, compared with the control group at most assessment points. Working alliance ratings with the online therapist were high.

The self-help intervention everyBody Plus, delivered with relatively standardised online guidance, can help bridge treatment gaps for patients with bulimic-spectrum eating disorders, and achieve faster and greater reductions in core symptoms.

Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing.

Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing.

One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = –0.89) and concerns around eating (d = –1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group.

Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.

Availability of long-term psychological interventions for personality disorders is limited because of their high intensity and cost. Research in evidence-based, low-intensity interventions is needed.

This study aimed to examine the feasibility, acceptability and potential impact of a low-intensity, digital guided self-help (GSH) intervention that is focused on emotion regulation, recovery-oriented and provides in-the-moment delivery for patients with personality disorders.

We conducted a single-blind feasibility trial. A total of 43 patients with a personality disorder were recruited and randomly assigned to either a GSH arm (n = 22) or a treatment-as-usual arm (n = 21). The GSH intervention included a series of short videos offering psychoeducation and support, personalised feedback using text messages, and supportive telephone calls, for 4 weeks in addition to treatment as usual. Outcomes of emotional disturbance, emotion dysregulation, self-harm behaviours and decentring ability were measured at baseline, 4 weeks (end of intervention) and 8 weeks (follow-up).

All patients who attended the first session continued until the last session. There was an interaction effect between time and group on anxiety (P = 0.027, Δη2 = 0.10), where the GSH group showed a significant reduction in anxiety at follow-up (P = 0.003, d = 0.25). The GSH group increased in decentring ability at the end of intervention (P = 0.007, d = −0.65), and the decrease in self-harm behaviours continued until follow-up (P = 0.02, d = 0.57).

The results suggest that a personalised digital GSH with a focus on recovery could reduce anxiety and self-harm behaviours at short-term follow-up.

Behavioural activation (BA) is recommended by the National Institute for Health and Care Excellence guidelines for the treatment of perinatal depression; however, there is limited evidence about whether it is effective when delivered by non-mental health specialists (NMHS) in a perinatal setting in the UK.

This study aimed to adapt a BA intervention manual and guided self-help booklet intended for delivery by NMHSs for the treatment of perinatal depression.

Interviews were conducted with 15 women and 19 healthcare professionals (HCP) within the first study element. Four experience-based co-design (EBCD) workshops were held, with the involvement of 14 women and three HCPs, to modify the BA documents for the specific needs of perinatal women. Thematic analysis was used to analyse the data.

The findings from the study elements were presented with themes. The co-designers (women and HCPs) pointed out that having sleeping problems, changes in appetite, feeling exhausted and feeling emotional, may be experienced by non-depressed mothers as well during pregnancy or in the postpartum period, especially around the fourth day after giving birth. Therefore, it was important to differentiate these feelings from depression. The women also wanted to see an example for each activity before being asked to do it. Having examples would help them to see the possibilities before creating their own diary sheets or tables of activities.

Aside of the tool adaptation, the findings of this study provide a foundation to assess the effectiveness of the adapted intervention in a subsequent feasibility trial.

Cognitive behaviour therapy (CBT), self-help and guided self-help interventions have been found to be efficacious and cost effective for victims of trauma, but there are limited data from low- and middle-income countries on culturally adapted interventions for trauma.

To investigate the feasibility and acceptability of culturally adapted trauma-focused CBT-based guided self-help (CatCBT GSH) for female victims of domestic violence in Pakistan.

This randomized controlled trial (RCT) recruited 50 participants from shelter homes in Karachi and randomized them to two equal groups. The intervention group received GSH in nine sessions over 12 weeks. The control group was a waitlist control. The primary outcomes were feasibility and acceptability. Secondary outcomes included Impact of Event Scale-Revised (IES-R), Hospital Anxiety and Depression Scale (HADS) and the WHO Disability Assessment Schedule 2 (WHO DAS 2). Assessments were carried out at baseline and at 12 weeks.

Out of 60 clients who met DSM-5 criteria for post-traumatic stress disorder (PTSD), 56 (93.3%) agreed to participate in the study. Retention to the intervention group was excellent, with 92% (23/25) attending more than six sessions. Statistically significant differences were noted post-intervention in secondary outcomes in favour of the intervention.

A trial of CatCBT GSH was feasible and the intervention was acceptable to Pakistani women who had experienced domestic violence. Furthermore, it may be helpful in improving symptoms of PTSD, depression, anxiety and overall functioning in this population. The results provide a rationale for a larger, confirmatory RCT of CatCBT GSH.

Social anxiety is common among adolescents in Pakistan and is associated with low self-esteem. Among the recommended treatments, cognitive behavioural therapy (CBT) is effective, and self-help approaches are encouraged.

To determine the effectiveness of culturally adapted CBT-based guided self-help (CACBT-GSH) intervention, using a manual ‘Khushi aur Khatoon’, for treating social anxiety when added to treatment as usual (TAU) compared with TAU only.

A total of 76 adolescents with social anxiety aged 13–16 years from six schools in Multan, Pakistan were recruited into this randomized controlled trial. Participants were divided into intervention and control groups in a 1:1 ratio. Social anxiety, self-esteem and fear of negative evaluation were assessed through the Liebowtiz Social Anxiety Scale for children and adolescents, the Rosenberg Self-Esteem Scale and the Brief Fear of Negative Evaluation, respectively, at baseline and at the end of the study. Guided self-help using culturally adapted CBT (CACBT)-based self-help manual (eight sessions, one session per week) was provided to the intervention group. The effect of the CACBT-GSH intervention was analysed with ANCOVA.

There was a statistically significant difference between the intervention and the control groups in favour of intervention. Participants in the intervention group showed reduced symptoms of social anxiety (p < .001), fear of negative evaluation (p < .001) and enhanced self-esteem (p < .001).

The study demonstrated the effectiveness of CACBT-based guided self-help intervention in treating social anxiety and addressing the symptoms associated with it.

Common mental disorders (CMD) cause large suffering and high societal costs. Cognitive behavioural therapy (CBT) can effectively treat CMD, but access to treatment is insufficient. Guided self-help (GSH) CBT, has shown effects comparable with face-to-face CBT. However, not all patients respond to GSH, and stepping up non-responders to face-to-face CBT, could yield larger response rates. The aim was to test a stepped care model for CMD in primary care by first evaluating the effects of GSH-CBT and secondly, for non-responders, evaluating the additional effect of face-to-face CBT.

Consecutive patients (N = 396) with a principal disorder of depression, anxiety, insomnia, adjustment or exhaustion disorder were included. In Step I, all patients received GSH-CBT. In Step II, non-responders were randomized to face-to-face CBT or continued GSH. The primary outcome was remission status, defined as a score below a pre-established cutoff on a validated disorder-specific scale.

After GSH-CBT in Step I, 40% of patients were in remission. After Step II, 39% of patients following face-to-face CBT were in remission compared with 19% of patients after continued GSH (p = 0.004). Using this stepped care model required less than six therapy sessions per patient and led to an overall remission rate of 63%.

Stepped care can be effective and resource-efficient to treat CMD in primary care, leading to high remission rates with limited therapist resources. Face-to-face CBT speeded up recovery compared with continued GSH. At follow-ups after 6 and 12 months, remission rates were similar in the two groups.

Early weak treatment response is one of the few trans-diagnostic, treatment-agnostic predictors of poor outcome following a full treatment course. We sought to improve the outcome of clients with weak initial response to guided self-help cognitive behavior therapy (GSH).

One hundred and nine women with binge-eating disorder (BED) or bulimia nervosa (BN) (DSM-IV-TR) received 4 weeks of GSH. Based on their response, they were grouped into: (1) early strong responders who continued GSH (cGSH), and early weak responders randomized to (2) dialectical behavior therapy (DBT), or (3) individual and additional group cognitive behavior therapy (CBT+).

Baseline objective binge-eating-day (OBD) frequency was similar between DBT, CBT+ and cGSH. During treatment, OBD frequency reduction was significantly slower in DBT and CBT+ relative to cGSH. Relative to cGSH, OBD frequency was significantly greater at the end of DBT (d = 0.27) and CBT+ (d = 0.31) although these effects were small and within-treatment effects from baseline were large (d = 1.41, 0.95, 1.11, respectively). OBD improvements significantly diminished in all groups during 12 months follow-up but were significantly better sustained in DBT relative to cGSH (d = −0.43). At 6- and 12-month follow-up assessments, DBT, CBT and cGSH did not differ in OBD.

Early weak response to GSH may be overcome by additional intensive treatment. Evidence was insufficient to support superiority of either DBT or CBT+ for early weak responders relative to early strong responders in cGSH; both were helpful. Future studies using adaptive designs are needed to assess the use of early response to efficiently deliver care to large heterogeneous client groups.

To evaluate the clinical effectiveness and cost-effectiveness of Access to Psychological Services Ireland (APSI), a primary care adult psychology service.

A repeated measures design was used to evaluate the clinical outcomes of service users who completed an intervention. Psychological distress, depressive symptomatology and anxiety symptomatology were measured using the Clinical Outcomes in Routine Evaluation–Outcome Measure (CORE-OM), the Patient Health Questionnaire-9 (PHQ-9) and the Generalised Anxiety Disorder-7 (GAD-7), respectively. Self-reported health and economic outcomes were measured using the EQ-5D-3L and the Eco-Psy, respectively.

A total of 381 adults were assessed as suitable for an APSI intervention, with 198 (52%) of these completing at least one intervention. Significant reductions in psychological distress were observed for completers of guided self-help and brief cognitive behavioural therapy, with service users also showing significant reductions in anxiety and depressive symptomatology. Reliable and clinically significant change on the CORE-OM was observed for 67.9% of treatment completers. Service users reported significant improvements in their health status but did not show changes in their health service usage in the 3-month follow-up period.

APSI provided an accessible service model that was clinically effective in managing a range of mild to moderate mental health difficulties. The cost-effectiveness of the service model may be enhanced by offering a wider range of high-throughput interventions and by increasing the treatment completion rate.

The development of widely accessible, effective psychological interventions for depression is a priority. This randomized trial provides the first controlled data on an innovative cognitive bias modification (CBM) training guided self-help intervention for depression.

One hundred and twenty-one consecutively recruited participants meeting criteria for current major depression were randomly allocated to treatment as usual (TAU) or to TAU plus concreteness training (CNT) guided self-help or to TAU plus relaxation training (RT) guided self-help. CNT involved repeated practice at mental exercises designed to switch patients from an unhelpful abstract thinking habit to a helpful concrete thinking habit, thereby targeting depressogenic cognitive processes (rumination, overgeneralization).

The addition of CNT to TAU significantly improved depressive symptoms at post-treatment [mean difference on the Hamilton Rating Scale for Depression (HAMD) 4.28, 95% confidence interval (CI) 1.29–7.26], 3- and 6-month follow-ups, and for rumination and overgeneralization post-treatment. There was no difference in the reduction of symptoms between CNT and RT (mean difference on the HAMD 1.98, 95% CI −1.14 to 5.11), although CNT significantly reduced rumination and overgeneralization relative to RT post-treatment, suggesting a specific benefit on these cognitive processes.

This study provides preliminary evidence that CNT guided self-help may be a useful addition to TAU in treating major depression in primary care, although the effect was not significantly different from an existing active treatment (RT) matched for structural and common factors. Because of its relative brevity and distinct format, it may have value as an additional innovative approach to increase the accessibility of treatment choices for depression.

Although guided self-help for depression and anxiety disorders has been examined in many studies, it is not clear whether it is equally effective as face-to-face treatments.

We conducted a meta-analysis of randomized controlled trials in which the effects of guided self-help on depression and anxiety were compared directly with face-to-face psychotherapies for depression and anxiety disorders. A systematic search in bibliographical databases (PubMed, PsycINFO, EMBASE, Cochrane) resulted in 21 studies with 810 participants.

The overall effect size indicating the difference between guided self-help and face-to-face psychotherapy at post-test was d=−0.02, in favour of guided self-help. At follow-up (up to 1 year) no significant difference was found either. No significant difference was found between the drop-out rates in the two treatments formats.

It seems safe to conclude that guided self-help and face-to-face treatments can have comparable effects. It is time to start thinking about implementation in routine care.
