Internalizing problems, externalizing problems, and prosocial behavior - three dimensions of the strengths and difficulties questionnaire (SDQ): A study among South African adolescents.

This study aimed to examine the factor structure of the Strengths and Difficulties Questionnaire Self-Report version (SDQ-S), its psychometric properties and measurement invariance by gender and language spoken at home, among secondary school students in Western Cape, South Africa. A sample of 3,542 adolescents in Grade 8 (Mean age = 13.7 years) completed the SDQ-S in a three-language questionnaire (Afrikaans, English and isiXhosa). The data were collected from 42 secondary schools in Cape Town, South Africa. Confirmatory factor analyses with the WLSMV estimator with adjustment for cluster effects (schools) were applied. The SDQ-S was originally developed to cover five domains: four "difficulty" domains (hyperactivity/inattention, emotional, conduct, and peer) and one "strengths" domain (prosocial behavior). When the five factors were tested on the data for the current study, poor fit was obtained. After excluding four items, a three-factor solution with no cross-loadings and no correlated error terms obtained acceptable fit. The results are consistent with previous studies. Strong measurement invariance across genders and language spoken at home was confirmed. In studies of community samples, the use of the SDQ-S scale as an instrument with a three-factor dimension (internalizing, externalizing and prosocial) may be more appropriate than using the original five-factor model.

Effect of the PREPARE intervention on sexual initiation and condom use among adolescents aged 12-14: a cluster randomised controlled trial in Dar es Salaam, Tanzania.

BACKGROUND: Unsafe sexual practices continue to put adolescents at risk for a number of negative health outcomes in Tanzania. While there are some effective theory-based intervention packages with positive impact on important mediators of sexual behaviours, a context specific and tested intervention is urgently needed in Tanzania. PURPOSE: To develop and evaluate an intervention that will have a significant effect in reducing sexual initiation and promoting condom use among adolescents aged 12-14 in Dar es Salaam, Tanzania. DESIGN: A school-based Cluster Randomised Controlled Trial was conducted during 2011-2014 in Kinondoni Municipality. METHODS: A total of 38 public primary schools were randomly selected, of which half were assigned to the intervention and half to the control group based on their size and geographic location. Participants were interviewed using a self-administered questionnaire at baseline before the PREPARE intervention and then, 6 and 12 months following intervention. The primary outcomes were self-reported sex initiation and condom use during the past 6 months. Data analysis was done using Generalized Estimating Equation (GEE) modelling controlling for repeated measures and clustering of students within schools. RESULTS: A total of 5091 students were recruited at baseline, and interviewed again at 6 (n = 4783) and 12 months (n = 4370). Mean age of participants at baseline was 12.4 years. Baseline sociodemographic, psychometric and behavioural characteristics did not significantly differ between the two study arms. The GEE analysis indicated that the intervention had a significant effect on sexual initiation in both sexes after controlling for clustering and correlated repeated measures. A significantly higher level of action planning to use condoms was reported among female adolescent in the intervention arm than those in the control arm (p = 0.042). An effect on condom use behaviour was observed among male adolescent (p = 0.004), but not among female (p = 0.463). CONCLUSIONS: The PREPARE intervention had an effect in delaying self-reported sexual initiation among adolescents aged 12-14 in Dar es Salaam Tanzania. The intervention positively influenced action planning to use condoms for both sexes and increased actual condom use among male adolescents only. Future interventions addressing adolescent sexual and reproductive health should focus on impacting mediators of behaviour change.

Social Cognition Variables and Victimization as Predictors of Sexual Debut Among Adolescents in South Africa and Tanzania: A Multi-group SEM Analysis.

Early sexual debut is common in South Africa and Tanzania, with potentially negative reproductive health outcomes. The role of violence as a predictor of sexual debut was studied, in a context of predictors borrowed from social cognition models. Data were taken from cluster-randomized trials of school-based HIV prevention interventions in three sites in South Africa and Tanzania. Analyses consisted of descriptive statistics and multi-group structural equation modelling. The basic model functioned fairly well for Cape Town, but less well for Mankweng and Dar es Salaam (low R(2) values). Attitudes were the strongest predictor of intention. Adding socio-demographic variables to the model did not reduce the associations much and neither did subsequent inclusion of violence. Sexual debut was strongly associated with victimization; adding violence also substantially increased R(2) for sexual debut. Besides social cognition factors, intimate partner violence should be addressed in future research on reproductive health interventions for adolescents.

Associations between attitudes toward violence and intimate partner violence in South Africa and Tanzania.

Attitude change approaches are common in the prevention of intimate partner violence (IPV) among adolescents. This study examined associations between perpetration or victimization and attitudes toward IPV with data from a longitudinal randomized controlled trial (RCT) of an HIV prevention intervention among school students in three sites in South Africa and Tanzania. Data analyses were confined to students from the control group only, and to those with experience with romantic relationships. Boys and those more involved with violence reported more violence-supportive attitudes. For Cape Town (and to some extent Mankweng), the results of prospective prediction are consistent with the notion of a bidirectional attitudes-behavior interrelationship. For Dar es Salaam attitudes predicted behavior prospectively; however, prediction in the opposite direction was not confirmed. These results indicate that attitude change strategies may be useful complementary to structural approaches also in global South settings, although their effectiveness may vary.
