Measurement invariance of the group climate inventory across adults with and without mild intellectual disability in secure residential facilities.

BACKGROUND: The Group Climate Inventory (GCI) was tested for measurement invariance across 332 adults with and 225 adults without mild intellectual disabilities in Dutch forensic treatment, and for latent mean differences on its Support, Growth, Repression, and Atmosphere subscales. METHOD: Multigroup confirmatory factor analysis was used to evaluate the configural, threshold, and loading and threshold invariance of the GCI across both groups, and to compare group latent means on each subscale. RESULTS: Measurement invariance was found across groups. Latent mean group comparisons showed small but significant differences reflected in lower scores on Support and Atmosphere in the group with mild intellectual disabilities. CONCLUSION: The GCI allows meaningful comparisons between clients with and without mild intellectual disabilities in secure facilities. Results from the between-group comparisons suggest that consideration should be given as to whether, and why, the support and atmosphere perceptions of clients with mild intellectual disabilities might be less good.

Group climate, aggressive incidents and coercion in a secure forensic setting for individuals with mild intellectual disability or borderline intellectual functioning: A multilevel study.

BACKGROUND: This study examines associations between group climate, aggressive incidents and coercive measures in adults with mild intellectual disability or borderline intellectual functioning (MID-BIF) of a secure forensic setting. METHOD: Participants (N = 248) were interviewed about their perception of group climate utilizing the Group Climate Instrument. Data on aggressive incidents and coercive measures were retrieved from the facilities' electronic database. A multilevel structural equation model was fitted in which variability in perception of group climate within and between living groups was examined. RESULTS: An open and therapeutic group climate was associated with lower levels of aggression within and between groups. A higher number of aggressive incidents were significantly associated with a higher number of coercive measures. CONCLUSIONS: The findings have implications for the understanding of how group climate may play a role in reducing aggressive incidents at the living group in treatment of individuals with MID-BIF in secure forensic settings.

Parental solicitation, parental control, child disclosure, and substance use: native and immigrant Dutch adolescents.

OBJECTIVES: The present study examined whether the relation of parental solicitation, parental control, and child disclosure with adolescent alcohol and cannabis use is similar for native and non-Western immigrant Dutch adolescents. DESIGN: Questionnaire data from two study-samples were used with a combined sample of 705 adolescents (mean age 16.2 years; 47.2% female; 25.2% non-Western immigrant background). RESULTS: Native Dutch adolescents reported more weekly alcohol use than immigrant adolescents, while rates of cannabis use by native and immigrant adolescents were similar. Immigrant females reported lower levels of parental solicitation and child disclosure, but higher levels of parental control than native females. There were no differences in the sources of parental knowledge between native and immigrant males. Regression analyses showed no significant interaction effects of parental solicitation, parental control, or child disclosure with ethnic background for both alcohol and cannabis use (all p values > .05). CONCLUSION: Despite mean level differences in various factors, we did not find evidence of an interaction effect of the sources of parental knowledge with ethnic background on alcohol and cannabis use. This suggests that theories and prevention strategies focusing on these sources of parental knowledge in relation to substance use can be applicable to both native and immigrant Dutch adolescents.

Effects of viewing a pro-ana website: an experimental study on body satisfaction, affect, and appearance self-efficacy.

Pro-anorexia websites portray an extreme form of thin-ideal. This between-subjects experiment examined the effects of viewing such a website on body satisfaction, affect, and appearance self-efficacy compared to viewing control websites (fashion, home decoration, automutilation). The sample consisted of 124 normal weight, young adult, Dutch women (mean age 21.2, mean body mass index 21.4). Participants did not differ on affect and appearance self-efficacy. One body satisfaction measure showed that pro-anorexia viewers were more satisfied with their bodies than home decoration viewers. Our findings suggest that viewing a pro-anorexia website might not have detrimental effects on body satisfaction and affect among normal weight young women.

Alcohol use of immigrant youths in The Netherlands: The roles of parents and peers across different ethnic backgrounds.

INTRODUCTION AND AIMS: The aims of this study were to examine the roles of parental permissiveness toward alcohol use and affiliation with alcohol-using peers in alcohol use in youths from various ethnic backgrounds, and whether the role of peers was moderated by parental permissiveness. In addition, differences in these associations between native Dutch and non-Western immigrant youths were examined. DESIGN AND METHODS: Cross-sectional data of 578 youths with Surinamese, Moroccan, Turkish, Antillean and Asian backgrounds and 81 native Dutch were used, all aged 15-24. Alcohol use, affiliation with alcohol-using peers and parental permissiveness were measured using self-report questionnaires. Regression models controlled for age, religiousness, education level and parental alcohol use. Because of very low levels of alcohol use, data from Turkish and Moroccan immigrants were aggregated, and logistic regression analyses were performed. RESULTS: Parental permissiveness and affiliation with alcohol-using peers were positively related to level of alcohol use in youths with Surinamese, Antillean and Asian backgrounds and played an equally strong role in native Dutch youths with one exception. In Surinamese youths, parental permissiveness was more strongly related to alcohol use than in native Dutch youths. In youths with a Turkish/Moroccan background, parental permissiveness and affiliation with alcohol-using peers were strongly associated with any (versus no) alcohol use. Only parental permissiveness was, equally strong, associated with any alcohol use in native Dutch youths. DISCUSSION AND CONCLUSIONS: Irrespective of ethnic background and differences in level of alcohol use, parental permissiveness and affiliation with alcohol-using peers are related to youth alcohol use.

The influence of age and gender on the likelihood of endorsing cannabis abuse/dependence criteria.

INTRODUCTION: Higher prevalence rates of cannabis abuse/dependence and abuse/dependence criteria in 18-24year old versus older cannabis users and in males versus females might reflect true differences in the prevalence of these disorders across age and gender or, alternatively, they could arise from age- and gender-related measurement bias. To understand differences in endorsement across important subgroups, we examined the influence of age and gender simultaneously on the likelihood of endorsement of the various abuse/dependence criteria. METHOD: The sample consisted of 1603 adult past year cannabis users participating in the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a U.S. population study (39.6% aged 18-24; 62.1% male). Past year DSM-IV cannabis abuse/dependence criteria and withdrawal were assessed with the AUDADIS-IV. A restricted factor analysis with latent moderated structures was used to detect measurement bias. RESULTS: Although cannabis abuse and dependence diagnoses and various individual abuse/dependence criteria showed different prevalence rates across younger and older male and female cannabis users, none of the items showed uniform or non-uniform measurement bias with respect to age or gender. CONCLUSION: The results indicate that, although prevalence rates of cannabis abuse/dependence criteria differ across age and gender, past year abuse/dependence criteria function similarly across these groups. It can thus be concluded that the criteria are applicable to younger and older, as well as male and female, adult cannabis users.

Recent cannabis use among adolescent and young adult immigrants in the Netherlands--the roles of acculturation strategy and linguistic acculturation.

BACKGROUND: The present study examined the relation between two different acculturation measures (i.e., linguistic acculturation and the acculturation strategies integration, separation and marginalization) and past year cannabis use. Additionally, we studied the mediating role of affiliation with cannabis-using peers. METHOD: Data were utilized from i4culture, a Dutch study on immigrant adolescents and young adults aged 15-24 years. Participants belonged to the five largest immigrant populations in the Netherlands, living in or around the four major Dutch cities: Amsterdam, the Hague, Rotterdam, and Utrecht. In total, 771 adolescents and young adults (mean age 19.29, SD=2.61, 53.8% female) from Surinamese (n=210, 27.2%), Moroccan (n=209, 27.1%), Turkish (n=110, 14.3%), Antillean (n=109, 14.1%), and Asian (n=133, 17.3%) backgrounds participated. With questionnaires, past year cannabis use, acculturation strategy, linguistic acculturation, and affiliation with cannabis-using peers were assessed. RESULTS: Using logistic regression analyses, we found no relation between acculturation strategy and past year cannabis use (OR=1.25, p=0.38 for separation vs integration and OR=0.86, p=0.50 for marginalization vs integration). Linguistic acculturation was positively related to cannabis use (OR=2.20, p<0.01). Affiliation with cannabis-using peers partly mediated this relation (OR=1.09, p<0.01). CONCLUSIONS: Non-Western immigrant youngsters who speak the host culture's language at home are more likely to use cannabis than youngsters who speak their native language at home. The former group is more likely to affiliate with cannabis-using peers, which partly explains their increased risk of cannabis use.
