Growing research indicates that police legitimacy is a strong predictor of whether people behave respecting or violating rules. Perceptions of legitimacy are an output of socializing processes through which individuals develop their values and orientations toward authorities and the legal system. Legal socialization studies show that encounters with legal authorities are critical “teachable moments” in this process. The present study verifies whether direct or vicarious negative contacts with police officers affect changes in the perception of the legitimacy of police authority by adolescents over time. The adolescents were classified according to whether or not they had witnessed or experienced any negative contact or experience with the police during the period before the interview, composing two group trajectories at the first wave, four at the second wave, and eight at the third wave. Then the trajectories were compared in terms of the extent to which they agree with statements about police legitimacy, allowing the quantification of changes of opinion after negative contacts with the police. Results show that three main factors diminish the perception of police legitimacy: having negative contact with the police; having more than one negative contact; and having a recent negative contact. These findings have important implications for police patrolling and approach strategies.

Les résultats d’une étude constituant un suivi longitudinal prospectif d’une cohorte de dyades de mères présentant une pathologie borderline/limite avec leur enfant, dans une approche comparative avec une population témoin de dyades avec des mères sans trouble psychique apporte des pistes de réflexion sur les mécanismes d’une possible transmission de ces pathologies. Les interactions précoces à 3 mois au Still-face permettent d’appréhender comment les bébés peuvent précocement présenter des difficultés en lien avec des particularités du fonctionnement intrapsychique et interpersonnel maternel impactant la régulation émotionnelle dyadique. La grossesse, crise identitaire et narcissique, ébranle l’identité de ces mères aux pathologies limites déjà fragilisée par un narcissisme défaillant. Le bébé, par la relation de dépendance qu’il lui impose, réactive les particularités du fonctionnement interpersonnel de cette dernière et propre à cette pathologie. Les interactions précoces reflèteraient l’incapacité maternelle à s’accorder aux rythmes propres et aux mouvements affectifs et émotionnels de leur enfant. La notion de partage intersubjectif troublé éclaire la façon dont nous pouvons envisager les difficultés maternelles à aider le bébé à réguler ses émotions. Cette étude, par l’utilisation du protocole de la situation étrange, donne également un éclairage sur la manière dont les comportements d’attachement de ces enfants, à 13 mois, s’ancrent dans la particularité de ces dysfonctionnements interactifs. L’évaluation des représentations d’attachement et de la narrativité des enfants, entre 4 et 8 ans, met en lumière différentes évolutions dans la qualité de leur attachement. Ces différents résultats soulèvent, d’une part, la question de la transmission intergénérationnelle des modalités d’attachement – avec l’importance de sa qualité et des capacités de fonction réflexive maternelles – et d’autre part, celle de la désorganisation de l’attachement dans les pathologies limites. Enfin, une approche psychodynamique des narratifs des enfants au test des histoires à compléter éclaire les particularités de leur fonctionnement psychique.

We validated seven chronic disease ascertainment algorithms for use in the Canadian Longitudinal Study on Aging. The algorithms pertained to diabetes mellitus type 2, parkinsonism, chronic airflow obstruction (CAO), hand osteoarthritis (OA), hip OA, knee OA, and ischemic heart disease. Our target recruitment was 20 cases and controls per disease; some cases were controls for unrelated diseases. Participants completed interviewer-administered disease symptom and medication use questionnaires. Diabetes cases and controls underwent fasting glucose testing; CAO cases and controls underwent spirometry testing. For each disease, the appropriate algorithm was used to classify participants’ disease status (positive or negative for disease). We also calculated sensitivity and specificity using physician diagnosis as the reference standard. The final sample involved 176 participants recruited in three Canadian cities between 2009 and 2011. Most estimated sensitivities and specificities were 80 per cent or more, indicating that the seven algorithms correctly identified individuals with the target disease.

In this study we examined the longitudinal relationships between five dimensions of social support and psychological distress to determine whether (1) social support was related to subsequent psychological distress levels; or (2) if distress levels were related to subsequent social support levels; or (3) if distress and support had a reciprocal (bi-directional) relationship across time. Using bivariate autoregressive cross-lagged models, we analysed data from 2,564 older adults. We found support for the reciprocal relationship between affectionate support and distress. Higher psychological distress was related to subsequently higher levels of positive social interaction, and significantly related to subsequently higher emotional/informational support. No significant relationship was found between tangible and structural support and psychological distress. This study demonstrates that different types of support are associated in correspondingly different ways with psychological distress, and that psychological distress may be important in predicting levels of social support two years later.

Vers 2031, les personnes les plus âgées (85 ans et plus) pourraient composer 4 pourcent de la population totale du Canada. Ce document relève les changements constates dans le domaine de l'utilisation des soins de longue durée, des activités de la vie quotidienne (AVQ) et des activités instrumentales de la vie quotidienne (ATVQ) chez les participants les plus âgés du Aging in Manitoba Longitudinal Study, d'après trois éléments répartis sur 13 ans. Parmi les participants, 38,4 pour cent n'avaient pas eu recours aux soins de longue durée pendant la période examinée; entre 75 et 88 pour cent des participants pouvaient continuer à manger, à se déplacer dans leur maison et à se mettre au lit et à en sortir sans aide. En ce qui a trait aux activités instrumentales de la vie quotidienne, la proportion des gens qui n'avait pas besoin d'aide allait de 3 pour cent (réparations dans la maison) à 58 pour cent (se préparer une tasse de thé ou de café). Les résultats de ces analyses signalent l'hétérogénéité des aptitudes fonctionnelles des personnes très âgées et viennent enrichir la documentation portant sur cette tranche de la population.

Urinary incontinence is common in the elderly. The epidemiology of fecal and double (urinary and fecal) incontinence is less known. The Canadian Study of Health and Aging (CSHA) is a national study of elderly living in the community at baseline (n = 8,949) and interviewed in 1991–1992, 1996, and 2001. Using data from the CSHA, we report the prevalence of urinary, fecal, and double incontinence in each wave and the cumulative incidence between waves and investigate the predictors of urinary and fecal incontinence. Urinary incontinence increased rapidly in old age, being almost twice as high in women as in men. Fecal and double incontinence were less common, but also increased rapidly with age. In women, parity showed a positive relationship with (prevalent) urinary incontinence. In men, diabetes was a risk factor for urinary and fecal incontinence. We conclude that urinary, fecal, and double incontinence increase rapidly with age and that inquiry about incontinence should be part of routine medical and nursing assessment of all elderly.

The Bangor Longitudinal Study of Ageing (BLSA), conducted in rural Wales from 1979 to 1999, followed a cohort of survivors from more than 500 people over 20 years. Using both quantitative and qualitative data from the study, the factors associated with increases and decreases in loneliness and social isolation were identified. The study was based on a population sample and survivors were followed up every 4 years. From 1983 to 1987, 30 people aged 75 and over in 1979 were studied intensively. The customary measure of loneliness was used, as well as an aggregate measure devised by the research team. Social isolation was similarly measured, using an aggregate measure. Respondents were assessed as demonstrating low, moderate, or high levels of loneliness or isolation. Subsequently, statistical models of loneliness and social isolation were developed. Some respondents were assessed as not experiencing social isolation or loneliness during the study. Others showed changes in levels. In this article, the data are explored, seeking factors associated with changes in social isolation and loneliness. Outcome measures of these two variables of interest are compared with items from the aggregate measures and other identifiable intervening variables. The article discusses which change variables contribute most to levels of isolation and loneliness and result in different combinations of these two outcomes. Implications for policy and practice are discussed.

Based on the national Canadian Study of Health and Aging, the objective of this study was to determine the importance of socio-demographic and medical factors, cognitive and functional status as predictors of the development of urinary incontinence, and to estimate five-year incidence by sex and age group. Participants from the Canadian Study of Health and Aging who underwent a clinical examination in 1992 and were continent for urine at the time were followed up and their continence status was again determined in 1997. Multivariate logistic regression models with daily incontinence and daily or less than daily incontinence as the outcomes were developed separately for male (n = 306) and female (n = 520) survivors. Predictor variables were introduced in the following chunks: socio-demographic factors; cognitive status; functional status, diabetes and stroke. Five-year cumulative incidence of daily and less than daily incontinence by sex and age group was also estimated. Results indicated that the incidence of urinary incontinence was higher in women than in men, and increased by age in both men and women. Especially among men, those in institutions were much more likely to develop urinary incontinence than those in the community. Incontinence increased dramatically with severity of dementia, less so with physical immobility. Diabetes mellitus was related to the development incontinence in men but not in women, prior stroke was related to development of incontinence in both sexes. It is concluded that urinary incontinence is common in older persons, and enquiries about its presence should be part of routine medical and nursing assessment of older persons. Those who develop incontinence commonly have dementia and are physically impaired. The extent of assessment and management should be carefully tailored to each individual patient.

As part of its recruitment process, the Canadian Longitudinal Study on Aging (CLSA) will face the challenge of screening out individuals who are sufficiently impaired in their ability to provide informed consent. In the process of developing the design of the CLSA, a review of the literature was performed with the goal of identifying currently existing telephone cognitive screening tools that can be used to identify eligible study participants for population-based research on aging. We identified 12 telephone screening tools, four of which were based on the Mini-Mental State Exam (MMSE) and eight that were based on other face-to-face screening tools. Characteristics – including the constructs measured, the length of time for administration, the scoring/classification scheme, and any information regarding the validation of each tool – were extracted and summarized.

Successful recruitment and retention for population-based longitudinal studies requires understanding facilitators and barriers to participation. This study explored Canadians’ views regarding one such study, the proposed Canadian Longitudinal Study on Aging (CLSA). Focus groups of participants ≥40 years of age were held in six proposed CLSA data collection sites (Halifax, Montreal, Hamilton, Winnipeg, Calgary, and Vancouver) to discuss participating in a long-term study of healthy aging. There was fundamental support for longitudinal research on health and aging. Altruism was a key motivation to participation, and universities were viewed as credible parties to conduct such studies. Participants had few worries about providing biological samples but expressed concern about potential misuse of genetic materials, commercialization of participant data, and privacy issues. These findings have already informed current, and will inform future, work on the CLSA, and will also provide useful information to researchers who undertake other population-based longitudinal studies.

In a longitudinal cohort study of young adults from the Canton of Zurich in Switzerland, the course of anxiety and depressive disorders was examined in 3 interviews over a period of 7 years. The 1-year prevalence rates of panic disorders (including a milder form), generalized anxiety disorder, major depression, and recurrent brief depression were similar from age 21–28 yr. Females prevailed among all diagnoses, their preponderance being strongest for mild panic and major depression. No differential course could be found for the 3 initial diagnostic groups in 1979: the pure anxiety disorders, the pure depression, and the mixed anxiety – depression. Their courses were very similar: 41–52'% recovered, 24–41% developed pure depression, 14–15% manifested a mixed anxious – depressive syndrome, and 5–10% manifested pure anxiety. Compared to controls, all 3 groups showed a tendency to develop into mixed cases and to manifest more recurrences. When the diagnostic information of all 3 interviews was cumulated into longitudinal diagnostic groups, however, differences emerged with respect to severity and chronicity of the disorders. Cases of mixed anxiety-depression were treated more often than cases of pure anxiety or pure depression. Furthermore, in a longitudinal perspective, the mixed cases received a diagnosis more frequently than the cases of pure anxiety disorders or pure depressive disorders, and thus were found to be more recurrent or chronic. With respect to course prediction, a single diagnosis does not differentiate sufficiently and more longitudinal diagnostic information should be taken into account to enhance the certainty of prediction of course and outcome.

Une étude longitudinale auprès de 327 adolescents scolarisés suivis de 16 à 18 ans a permis de mettre en évidence l’évolution de la consommation de drogue illicite et les facteurs liés à cet usage. Au total, à 18 ans, 26% des garçons et 16% des filles ont essayé la drogue au moins une fois dans leur vie, et respectivement 10 et 8% en ont pris urant plusieurs périodes de l’enquête. L’expérimentation d’une drogue illicite est peu corrélée aux variables socioemographiques de la famille, ce que traduit l’homogénéisation de la population qui en fait l’essai. En revanche, les jeunes consommateurs se caractérisent par un mode de vie centré sur les relations avec les pairs, mettant l’accent sur la sphère relationnelle au détriment des relations familiales et de l’intérêt pour leur scolarité. L’alcoolisation et le tabagisme précoce sont des facteurs prédictifs de l’usage (unique mais surtout répété) d’une drogue illicite. De même que le cumul des problèmes de santé (dépressivité, troubles du sommeil, troubles somatiques). Toutefois, pour l’ensemble e ces variables corrélées à l’essai d’une drogue illicite, une prédictivité différentielle selon le sexe est observée. La consultation médicale augmente après l’usage répété de drogue. Les jeunes expérimentateurs conservent un contact Privilégié avec leurs parents et avec les jeunes en cas de problèmes (scolaire, santé, sentimentaux, graves). Il est discuté a Place des parents, des adultes responsables (médecins, professionnels de la santé, enseignants) et des pairs dans une Prévention précoce des difficultés de l’adolescent.
