Youth mental health in a Canadian community sample during COVID-19: Exploring the role of perceived sense of belonging.

Research has linked broad societal changes related to the COVID-19 pandemic and poorer mental health in young people. There remains a pressing need for studies examining the factors that are associated with better mental health and well-being. The current study addresses this gap using a community-based survey called the Waterloo Region Youth Impact Survey. It was designed in partnership with local youth and the Canadian Index of Well-Being in accordance with United Nations International Children's Emergency Fund guidelines. Using a convenience sampling methodology, this survey was developed to explore the domains, rates, and correlates of well-being and mental health among youth during the pandemic (N = 297). Confirmatory factor analysis was used to identify dimensions related to children's social environment (friends, school, family), sense of belonging, mental health, and well-being. Subsequently, a mediation model was tested. The relationship between children's environments and mental health and well-being operated via perceived sense of belonging. Findings shed light on patterns of youth mental health and well-being during the pandemic, illustrating the role of belonging as a promotive factor with public health relevance.

Observations on Gender Variance in Chinese Community Children Measured by the Gender Identity Questionnaire for Children.

Few studies have examined how gender variance (GV), broadly defined as gender identity and behaviors (e.g., activities and preferences) that do not correspond with culturally defined gender norms, manifests in community samples, particularly in children and outside Western contexts. We present data based on the Gender Identity Questionnaire for Children (GIQC; Johnson et al., 2004) among 461 Chinese community children (4-12years old) to gauge how well the GIQC serves as a measure of GV and the prevalence of GV. We examined the descriptive scores of GV, its relationship to a gender-typing measure that has been validated in Chinese children (the Child Play Behavior and Activity Questionnaire, CPBAQ), the scores on the GIQC of children whose gender is incongruent with birth-assigned sex, and the binned category distributions (from gender-variant to gender-conforming) in comparison to a Canadian community sample (van der Miesen et al., 2018). The Chinese children on average scored toward the gender-conforming end and children assigned female at birth showed more GV than children assigned male at birth. More importantly, the GIQC appears to be a reliable and sensitive measure of GV in the Chinese sample. GIQC scores correlated significantly with CPBAQ scores and showed a very similar reliability coefficient, gender difference effect size, and bin distribution pattern as the Canadian reference sample. Also, children reported as gender/sex incongruent had the most gender-variant GIQC scores. Although clinically gender-referred Chinese children are required to establish culturally specific cutoff points, these findings provide initial evidence for the characteristics of GV, the applicability of the GIQC as a measure of GV in Chinese community children, and the comparisons of GIQC categories between Chinese and Canadian community samples.

Medicine for the soul: (Non)religious identity, coping, and mental health during the COVID-19 pandemic.

Although the threat and uncertainty of the COVID-19 pandemic has become a significant source of distress, using religion to cope may be associated with more positive health. Given the severity and chronicity of the pandemic, religious individuals may also have relied on a variety of non-religious coping methods. Much of the existing COVID-19 research overlooks the role of religious group membership and beliefs in relation to coping responses and associated mental health, with an additional lack of such research within the Canadian context. Thus, this cross-sectional study investigated relations among religiosity, stressor appraisals, (both religious and non-religious) coping strategies, mental and physical health in a religiously-diverse Canadian community sample (N = 280) during the pandemic's 2nd wave from March to June 2021. Numerous differences were apparent in appraisal-coping methods and health across five (non)religious groups (i.e., Atheists, Agnostics, "Spiritual but not religious", Christians, and those considered to be religious "Minorities" in Canada). Religiosity was also associated with better mental health, appraisals of the pandemic as a challenge from which one might learn or grow, and a greater reliance on problem-focused, emotional-engagement, and religious coping. Moreover, both problem-focused and emotional-engagement coping mediated the relations between religiosity and health. Taken together, this research has implications for individual-level coping as well as informing culturally-sensitive public health messages promoting targeted self-care recommendations with integrated religious or spiritual elements during times of threat and uncertainty, such as the COVID-19 pandemic.

Psychometric soundness and predictive factors of the NCAST Parent-Child Interaction Teaching Scale in urban Chinese population.

Quality of parent-child interaction in early childhood functions as a critical indicator of nurturing care and is strongly associated with short-term and long-term development (health, cognition, language, social emotion, well-being, etc.). NCAST PCI Teaching Scale (PCI-TS), a video-based assessment regarded as a gold standard to measure PCI, has been widely used worldwide. However, its psychometric soundness among the urban Chinese population is unclear. This study assesses the PCI-TS's reliability and validity and explores predictive factors among urban Chinese parent-child dyads. PCI-TS was adopted to code mother-child interaction among urban Chinese dyads recruited during the children's regular health checks in local maternal and child health centres. Reliability was evaluated by internal consistency (Cronbach'α coefficient) and test-retest reliability (Pearson correlation) with an average interval of 18 days. Score distribution of each subscale and total scale were compared with NCAST Database and Canadian community sample by single sample t-test. Criteria-related validity was conducted by Infant-Toddler Home Observation Measurement of the Environment (Pearson correlation). Predictive factors was performed by multiple linear regression. Four hundred and twenty-nine eligible mother-child dyads were included for data analysis among the 466 recruited samples. Four qualified local paediatricians accomplished video coding with an average agreement of 86%. The PCI-TS has strong reliability among the Chinese population with the Cronbach'α coefficients of the Caregiver-Infant total score, Caregiver total and Infant total scores of 0.81, 0.81 and 0.74, respectively; an acceptable test-retest reliability (r = 0.73, p < 0.01); and moderate correlation with IT-HOME, ranging from 0.53 to 0.62. Child age, birth weight, maternal education, full-time housewife, living with grandparent(s) and living space were predictive factors on PCI-TS in the Chinese population. PCI-TS showed good psychometric properties for measuring mother-child interactions among urban Chinese dyads, offering clinicians and researchers a practical tool to evaluate PCI objectively. Child age, maternal education and living space were beneficial factors, while full-time mothers and living with grandparent(s) were risk factors.

Is Sexual Aversion a Distinct Disorder or a Trans-Diagnostic Symptom across Sexual Dysfunctions? A Latent Class Analysis

Sexual aversion disorder (SAD) is a chronic condition that impacts sexual and psychological well-being. However, the relevance of SAD as a discrete disorder remains highly debated. This study aimed to clarify the status of SAD as either a distinct disorder or a trans-diagnostic symptom shared among sexual dysfunctions. This cross-sectional study used a latent class analysis approach among a Canadian community sample (n = 1,363) to identify how patterns of SAD symptoms (i.e., sexual fear, disgust, and avoidance) emerge across different spheres of sexual functioning (i.e., desire and arousal, erection or lubrication, genito-pelvic pain, and orgasm) and examine sociodemographic and psychosexual correlates of the identified classes. Examination of fit indices suggested four classes: Sexually functional, Impaired desire and responsiveness, Sexual aversion, and Comorbid sexual dysfunctions. Sexual aversion class members were more likely to be single, had experienced sexual assault in adulthood, and report lower levels of sexual satisfaction and psychological well-being, compared to Sexually functional class members. Results suggest that SAD is a distinct clinical syndrome, while its symptoms may co-occur with other sexual dysfunctions. To ensure that the needs of people with SAD are met with tailored treatment options, future nosography might consider reclassifying SAD as a specific disorder.

Reproductive Coercion by Intimate Partners: Prevalence and Correlates in Canadian Individuals with the Capacity to be Pregnant.

Despite the large body of research on violence against women, violence that specifically targets women's reproductive autonomy and control over their reproductive health, called reproductive coercion (RC), is poorly documented in Canada. The purpose of this study is to determine the prevalence of RC behaviors in an adult Canadian community sample and to explore associated factors. A self-report online questionnaire was administered from September 2020 to April 2021 in Quebec and Ontario, Canada. Participants were recruited via social media, sexual and reproductive health clinics, community-based anti-violence organizations, and the project's partner organizations. The questionnaire contained validated RC questionnaire items and new items drawn from previous qualitative work. The sample comprised 427 participants, mostly self-identified as women (92%), aged 18 to 55 years (M = 29.01; SD = 6.64). Descriptive analyses and binary logistic regressions were conducted using SPSS 27. The results of this study show that 63.9% of participants reported at least one lifetime experience of RC. According to our data, contraceptive sabotage was the most common form (62.8%). Of the participants who had been pregnant, 9.8% reported control of pregnancy outcomes. Each RC category shows a different pattern of correlates. The findings also reveal that intimate partner violence (IPV) increases the likelihood of contraceptive sabotage. Moreover, the study suggests that low education level and IPV increase the risk for control of pregnancy outcomes. These findings underscore the importance of RC in the lives of many Canadian individuals with the capacity to be pregnant, and they highlight certain factors that place individuals at greater risk for RC. This knowledge can inform the development of prevention efforts and clinical interventions.

Believing in science: Linking religious beliefs and identity with vaccination intentions and trust in science during the COVID-19 pandemic.

Despite evidence supporting numerous scientific issues (e.g. climate change, vaccinations) many people still doubt the legitimacy of science. Moreover, individuals may be prone to scepticism about scientific findings that misalign with their ideological beliefs and identities. This research investigated whether trust in science (as well as government and media) and COVID-19 vaccination intentions varied as a function of (non)religious group identity, religiosity, religion-science compatibility beliefs, and/or political orientation in two online studies (N = 565) with university students and a Canadian community sample between January and June 2021. In both studies, vaccination intentions and trust in science varied as a function of (non)religious group identity and beliefs. Vaccine hesitancy was further linked to religiosity through a lack of trust in science. Given the ideological divides that the pandemic has exacerbated, this research has implications for informing public health strategies for relaying scientific findings to the public and encouraging vaccine uptake in culturally appropriate ways.

Maternal-Infant Attachment and its Relationships with Postpartum Depression, Anxiety, Affective Instability, Stress, and Social Support in a Canadian Community Sample.

As a crucial component of child development, maternal-infant attachment influences a child's cognitive, psychological, and social development. Maternal depression, anxiety, stress, and social support have been identified as risk factors for poor maternal-infant attachment in some studies, while others did not find such relationships. The aim of this study was to examine the associations of maternal-infant attachment with depression, anxiety, affective instability, stress, social support, and other variables in a community sample of Canadian postpartum women. A total of 108 Canadian postpartum women participated in this cross-sectional study. The Depression, Anxiety, and Stress Scale-21 (DASS-21) assessed depression, anxiety, and stress, and the Affective lability Scale-18 measured affective instability (AI). Multiple linear regression was conducted to examine the association between maternal-infant attachment and other variables. The findings revealed a significant association of maternal-infant attachment with postpartum depression, and infant temperament, while anxiety, AI, stress, and social support were not identified as predictors for maternal-infant attachment. The results implicate the importance of addressing maternal depression and maternal-infant attachment, consequently decreasing the risk for childhood psychopathology.

Is feeling bad good enough? Ethical guilt and callous-unemotional traits in childhood.

Lacking the capacity for guilt is a defining characteristic of callous-unemotional (CU) traits. Although guilt is a multifaceted construct, past CU research has rarely considered the reasons underlying children's negative emotional responses to wrongdoing. The present study investigated how different forms of guilt were associated with CU traits during early and middle childhood in a Canadian community sample. We interviewed 4- and 8-year-olds (N = 300; 50% female) to assess their emotion attributions and reasoning in response to hypothetical acts of aggression. Interview responses were used to calculate variables representing undifferentiated, ethical, and non-ethical guilt ratings. Caregivers rated children's CU tendencies at baseline and again 3 years later. Higher ethical guilt was associated with lower CU scores concurrently and 3 years later. Higher non-ethical guilt was associated with higher CU scores at baseline (for older children) and 3 years later (for all children). Undifferentiated guilt was not associated with CU after controlling for demographic variables.

French translation and validation of the International Trauma Questionnaire in a Canadian community sample

BackgroundThe diagnosis of complex post-traumatic stress disorder (CPTSD) was recently included into the 11th edition of the International Classification of Diseases (ICD-11). Recognizing the need for a brief and specific measure CPTSD symptoms as defined by the ICD-11, Cloitre and her team (2018) developed the original English version of the International Trauma Questionnaire (ITQ). The ITQ is composed of two scales—‘post-traumatic stress disorder (PTSD)’ and ‘disturbances in self-organization’ (DSO), respectively subdivided into three subscales. It was found to be psychometrically valid but has yet to be available in French. ObjectiveThe purpose of this study was to provide a French version of the ITQ and to examine its factorial validity, internal consistency, and convergent validity in a French-speaking Canadian sample. ParticipantsThe sample included 335 French-Canadian adults from the community. MethodsThe ITQ was translated in French, back translated into English, and deemed equivalent by the original ITQ's author. Participants answered the French version of the ITQ, as well as measures of convergent validity, via phone interview. ResultsConfirmatory factorial analyses revealed that the French ITQ presented the same factor structure as the original ITQ. Composite reliability scores revealed good internal consistency for both scales, and all but one subscale. Pearson's correlation and Steiger's Z test revealed good convergent validity. ConclusionThis study supports the factorial validity, internal consistency, and convergent validity of the French version of the ITQ, suggesting that it is a psychometrically sound measure of CPTSD.

Examining suicidal desire through the lens of the three-step theory: A cross-sectional and longitudinal investigation in a community sample.

Advancing evidence-based theories of suicide is critical to improving suicide prevention. The aim of the current study was to investigate suicidal desire through an emerging theory of suicide, the Three-Step Theory (3ST). Specifically, this study investigated the validity and predictive utility of Steps 1 and 2 of the 3ST in a Canadian community sample. Participants were 487 adults between the ages of 35 to 90 (M = 59; 64% female, 87% White) who completed self-report measures assessing suicidal ideation and attempt history, hopelessness, psychological pain, and 5 forms of social connectedness at baseline and 6 months later. In support of 3ST predictions, cross-sectional analyses showed (a) the combination of pain and hopelessness strongly correlated with suicidal desire, and (b) connectedness was protective of suicidal desire among those high in pain and hopelessness. Regarding predictive utility, longitudinal analyses showed that pain and hopelessness were strong predictors of future suicidal desire and that connectedness was protective against future suicidal desire. These relationships of pain, hopelessness, and connectedness remained when controlling for baseline suicidal desire. Results support the validity and predictive utility of 3ST hypotheses related to suicidal desire. Taken together with previous studies, findings suggest that Steps 1 and 2 are useful for conceptualizing suicide risk and prevention. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Clarifying the Relation Between Alcohol Demand and Alcohol-related Relative Reinforcement and Driving After Drinking in a Canadian Community Sample

ABSTRACTRésumé Objective: Previous studies examining associations between elevated behavioural economic alcohol demand and rates of driving after drinking (DAD) have primarily focused on university students in the United States. It is unclear whether similar associations exist in community adults and in other locations. Furthermore, the role of proportionate alcohol reinforcement (e.g., reinforcement derived from alcohol vs nonalcohol-related activities) has not been investigated in relation to DAD. The goal of this study was to investigate cognitive and behavioural economic factors related to DAD in a large community sample of Canadian adults. Methods: Participants (N = 926) were extracted from the “Population Assessment for Tomorrow's Health” registry, a sample of adults from the Hamilton, ON community. Primary assessments included a hypothetical alcohol purchase task assessing alcohol demand, the Adolescent Reinforcement Survey Schedule to assess proportionate alcohol reinforcement, a driving behaviours questionnaire assessing driving-related cognitions and DAD frequency. Results: In separate hierarchical regression models predicting DAD frequency and lifetime DAD quantity (adjusting for age, sex, income, and drinking quantity), individuals with elevated alcohol demand and alcohol-related reinforcement showed greater engagement in DAD. Importantly, relative reinforcement accounted for unique variance beyond alcohol demand. Conclusions: These results extend the established relationship between alcohol demand and DAD to a large sample of Canadian adults. Furthermore, this study is the first to establish a unique association between alcohol-related reinforcement and DAD. These results suggest that alcohol-related reinforcement may be a useful target for alcohol-impaired driving interventions. Objectif: Des études antérieures portant sur l’association entre la demande élevée d’alcool ayant une incidence sur le comportement et le taux élevé de conduite en état d’ébriété (DAD) étaient principalement axées sur les étudiants universitaires aux États-Unis. Il n’est pas clair si de telles associations existent au niveau des adultes de la communauté ou d’ailleurs. En outre, le rôle du renforcement proportionnel à l’alcool (par exemple, le renforcement dérivé d’activités liées à l’alcool par rapport à des activités non liées à l’alcool) n’a pas été étudié en relation avec la DAD. Le but de cette étude était d’étudier les facteurs d’économie cognitive et comportementale liés à la DAD dans un large échantillon d’adultes canadiens. Méthodes: Les participants (N = 926) ont été recueillis dans le registre «Évaluation de la population pour améliorer la santé de demain» (PATH), un échantillon d’adultes de la communauté de Hamilton, ON. Les évaluations primaires comprenaient une tâche d’achat d’alcool hypothétique visant à évaluer la demande d’alcool, le programme d’enquêtes sur le renforcement des capacités chez les adolescents pour comparer les résultats, un questionnaire sur les comportements de conduite routière évaluant les cognitions liées à la conduite et la fréquence des DAD. Résultats: Dans les modèles de régression hiérarchique distincts prédisant la fréquence et la quantité de DAD au cours de la vie (ajustement en fonction de l’âge, du sexe, du revenu et de la consommation), les individus avec une fréquence élevée d’alcool et un renforcement d’activités lié à l’alcool montraient un plus grand engagement dans DAD. Fait important, le renforcement relatif explique la variance unique par rapport à la demande d’alcool. Conclusions: Ces résultats renforcent la relation établie entre la consommation d’alcool et DAD à un large échantillon d’adultes canadiens. En outre, cette étude est la première à établir une association unique entre le renforcement lié à l’alcool et le DAD. Ces résultats suggèrent que le renforcement lié à l’alcool pourrait être une cible utile pour les interventions de conduite routière avec facultés affaiblies par l’alcool.

Blood Lithium Monitoring Practices in a Population-Based Sample of Older Adults.

Lithium is an effective treatment for mood disorders, but lithium level and renal monitoring every 3 months is recommended in older patients treated with lithium to prevent serious adverse events. This study examined lithium monitoring practices in a large geriatric cohort. This population-based cohort study (N = 11,006) used linked health care administrative databases. Older lithium users (n = 5,503; mean age = 70.6 years) in Ontario, Canada, enrolled between April 1, 2002, and March 31, 2014, were propensity score matched 1:1 to valproate users (n = 5,503). The frequency with which serum lithium levels were monitored and renal and endocrine laboratory testing was done during a 1-year follow-up period was examined. The baseline characteristics of the 2 groups were similar. At least 1 serum lithium concentration recorded within 90, 180, and 365 days of follow-up was present in 24.1%, 42.4%, and 66.8% of lithium users, respectively. Corresponding numbers for serum creatinine were 29.6%, 50.4%, and 75.4%, respectively. While serum creatinine monitoring (hazard ratio [HR] = 1.19; 95% CI, 1.12-1.27; P < .001), thyroid-stimulating hormone monitoring (HR = 1.47; 95% CI, 1.37-1.58; P < .001), and calcium testing (HR = 1.15; 95% CI, 1.02-1.29; P = .018) were statistically higher in lithium compared to valproate users, absolute differences between groups were not clinically meaningful. In a geriatric Canadian community sample, lithium monitoring was infrequent and inconsistent with international standards that call for screening of lithium levels and renal function every 3 months.

Depressive episodes, weight change, and incident diabetes in a Canadian community sample

IntroductionDepression has consistently been associated with an increased risk of diabetes in recent meta-analyses. However, depression is a highly heterogeneous construct and people with specific symptoms of depression, such as weight gain and increased sleep, may be at a higher risk of diabetes.&#x0D; Objectives and ApproachThis work will compare incident diabetes in Ontario adults with recent depressive episodes that included symptoms of weight gain, weight loss, or no weight change and in those with no recent depressive episodes. Participants will be drawn from several waves of the Canadian Community Health Survey and the National Population Health Survey. Past 12-month depressive episodes and weight change during most recent or worst episodes was measured using the CIDI/CIDI short form. Time to incident diabetes will be ascertained through linkage with the Ontario Diabetes Database. Cox proportional hazards regression will assess diabetes incidence by depression and weight change characteristics.&#x0D; ResultsThis study will include 106 084 Ontario adults who participated in the Canadian Community Health Survey (2000/2001, 2002, 2003, 2012) and the National Population Health Survey (1996). Follow-up time will range from 4 to 19 years (until March 2017). Study covariates will include demographic and lifestyle factors, comorbidities, and health care use and will be extracted from the surveys above and from administrative health data. The dataset for this study is currently being prepared by the Institute for Clinical Evaluative Sciences (ICES) and the findings of this analysis will be presented at this conference.&#x0D; Conclusion/ImplicationsThe results of this work will provide insight into who, among those with depression, is at highest risk of new-onset diabetes. These results will be relevant to the development of both personalized and population-level diabetes screening and prevention strategies.

Nursing Child Assessment Satellite Training Parent-Child Interaction Scales: Comparing American and Canadian Normative and High-Risk Samples

PurposeMany nurses rely on the American Nursing Child Assessment Satellite Training (NCAST) Parent-Child Interaction (PCI) Teaching and Feeding Scales to identify and target interventions for families affected by severe/chronic stressors (e.g. postpartum depression (PPD), intimate partner violence (IPV), low-income). However, the NCAST Database that provides normative data for comparisons may not apply to Canadian families. The purpose of this study was to compare NCAST PCI scores in Canadian and American samples and to assess the reliability of the NCAST PCI Scales in Canadian samples. MethodsThis secondary analysis employed independent samples t-tests (p < 0.005) to compare PCI between the American NCAST Database and Canadian high-risk (families with PPD, exposure to IPV or low-income) and community samples. Cronbach's alphas were calculated for the Canadian and American samples. ResultsIn both American and Canadian samples, belonging to a high-risk population reduced parents' abilities to engage in sensitive and responsive caregiving (i.e. healthy serve and return relationships) as measured by the PCI Scales. NCAST Database mothers were more effective at executing caregiving responsibilities during PCI compared to the Canadian community sample, while infants belonging to the Canadian community sample provided clearer cues to caregivers during PCI compared to those of the NCAST Database. Internal consistency coefficients for the Canadian samples were generally acceptable. ConclusionsThe NCAST Database can be reliably used for assessing PCI in normative and high-risk Canadian families. Practical implicationsCanadian nurses can be assured that the PCI Scales adequately identify risks and can help target interventions to promote optimal parent-child relationships and ultimately child development.

Attachment, trust, and satisfaction in relationships: Investigating actor, partner, and mediating effects

AbstractRomantic relationship dissatisfaction has been cited as a primary reason for seeking mental health services (H. M. Foran, M. A. Whisman, &amp; S. R. H. Beach, 2015). An increasing number of studies have revealed the importance of romantic attachment in understanding relationship satisfaction (M. Mikulincer &amp; P. R. Shaver, 2016). This study aims to assess dyadic trust as a possible mediator of the relation between insecure romantic attachment and relationship satisfaction within a Canadian community sample of 199 heterosexual couples. Results revealed significant actor and partner effects. Specifically, male and female attachment avoidance, as well as male attachment anxiety, predicted lower dyadic trust, which in turn predicted lower relationship satisfaction. These results add to the current literature, suggesting important gender differences in the effects attachment has on overall relationship satisfaction.

Opening the closet door: Openness to experience, masculinity, religiosity, and coming out among same-sex attracted men

Contemporary models of sexual identity emphasize variability in “coming out”. To date, little research has examined the potential role of personality and individual differences. In a Canadian community sample of same-sex attracted men (N=257), greater openness to experience (i.e., openness) and lower religiosity were associated with an earlier age of coming out. Further, openness was associated with an earlier age of coming out over and above childhood gender role, religiosity, and participant age. We also found a 3-way interaction, such that a particularly late age of coming out was found among highly masculine, highly religious men low in openness. Using a dichotomous measure, openness was also lower among those who had not come out (vs. those who were out). Our findings suggest potential barriers to coming out for same-sex attracted men with more conventional and traditional personality traits. Implications for understanding the coming out experience are discussed.

Child maltreatment and educational attainment in young adulthood: results from the Ontario Child Health Study.

There is increasing evidence for the adverse effects of child maltreatment on academic performance; however, most of these studies used selective samples and did not account for potential confounding or mediating factors. We examined the relationship between child physical abuse (PA; severe and non-severe) and sexual abuse (SA) and educational attainment (years of education, failure to graduate from high school) with a Canadian community sample. We used data from the Ontario Child Health Study (N = 1,893), a province-wide longitudinal survey. Potential confounding variables (family socio-demographic and parental capacity) and child-level characteristics were assessed in 1983, and child abuse was determined in 2000-2001 based on retrospective self-report. Results showed that PA and SA were associated with several factors indicative of social disadvantage in childhood. Multilevel regression analyses for years of education revealed a significant estimate for severe PA based on the unadjusted model (-0.60 years, 95% CI = [-0.45, -0.76]); estimates for non-severe PA (0.05 years, CI = [-0.15, 0.26]) and SA (-0.25 years, CI = [-0.09, -0.42]) were not significant. In the adjusted full model, the only association to reach significance was between severe PA and reduced years of education (-0.31 years, CI = [-0.18, -0.44]). Multilevel regression analyses for failure to graduate from high school showed significant unadjusted estimates for severe PA (OR = 1.77, 95% CI = [1.21, 2.58]) and non-severe PA (OR = 1.61, CI = [1.01, 2.57]); SA was not associated with this outcome (OR = 1.40, CI = [0.94, 2.07]). In the adjusted full models, there were no significant associations between child abuse variables and failure to graduate. The magnitude of effect of PA on both outcomes was reduced largely by child individual characteristics. These findings generally support earlier research, indicating the adverse effects of child maltreatment on educational attainment. Of particular note, severe PA was associated with reduced years of education after accounting for a comprehensive set of potential confounding variables and child characteristics.

Addiction Prone Personality characteristics and alcohol and marijuana dependence

The Addiction Prone Personality (APP) test was originally designed to identity prealcoholic personality characteristics, and was called the PREALC test. The name of this test was changed to the APP test when research showed that clinical samples that were addicted to drugs other than alcohol also had high scores. This investigation examines the ability of the APP test to discriminate between four groups: alcohol dependent, marijuana dependent, alcohol and marijuana dependent and neither alcohol nor marijuana dependent respondents in a young Canadian community sample (n = 461). Results showed that the all three alcohol & drug dependent groups scored higher on the APP than non-dependent participants, but that they did not differ from each other. Further analyses using the facets of the APP showed that marijuana dependence was not associated with sensation seeking and negative view of self, but was significantly associated with facets measuring impulsivity and lower self regulation.

Bouncing back: remission from depression in a 12-year panel study of a representative Canadian community sample

This study sought to investigate time to remission from depression in a community-based sample of adults followed for 12years. Data were derived from the National Population Health Survey (1994/5-2006/7 and 1996/7-2008/9). Fully 1,128 adults were included who were depressed at baseline according to DSM-III/CIDI-SF criteria. Kaplan-Meier and Cox proportional hazards procedures were used to determine time to remission and the demographic (e.g., gender and marital status), psychosocial (e.g., social support and adverse childhood experience) and health-related (e.g., pain, health conditions and alcohol use) factors with which it is associated. More than three quarters of the sample (77%) no longer screened positive for depression at 2years, and nearly the entire sample (94%) had remitted by 12years. Adverse childhood experiences (i.e., childhood abuse and parental additions), lack of social support, the presence of pain and health conditions (i.e., migraines, arthritis and back pain) each predicted more time to remission. The only factor associated with time to remission in the multivariate analysis was a history of childhood physical abuse. Most community members with depression get better after 2 years and nearly all will have remitted, at least once, by 12years. The results of this study may help guide the development of interventions for chronic depression that focus on early prevention of childhood abuse.
