Social skills and depressive symptoms across adolescence: social support as a mediator in girls versus boys.

The current population-based study of Norwegian adolescents examined gender-specific patterns in the prospective association between social skills in early adolescence (age 12.5; n = 566) and changes in depressive symptoms from early to late adolescence (age 16.5; n = 375). Further, a potential mediation effect of social support (from peers, parents, and teachers) in middle adolescence (age 14.5; n = 456) was examined. The findings indicated that low levels of social skills in early adolescence predicted increases in depressive symptoms for both girls and boys. Low levels of friend support in middle adolescence mediated this relationship for girls, but not boys. The findings underline the importance of including social skills training in primary programs designed to prevent development of depression. Preventive programs should also include actions on how girls can cope with interpersonal difficulties.

Trajectories of maternal symptoms of depression and anxiety over 13 years: the influence of stress, social support, and maternal temperament.

BACKGROUND: Depression and anxiety are the most common mental health problems among women, with various negative impacts both for the women concerned and their families. Greater understanding of developmental trajectories of maternal symptoms of depression and anxiety over the child rearing period would have significant benefits for public health, informing prevention and treatment approaches. The aim of the current study was to examine whether stressors related to child rearing and living conditions, social support, and maternal temperament, predicted mothers' membership in groups with different trajectories of symptoms of depression and anxiety during 13 years of the child rearing phase. METHODS: The data were from a prospective, longitudinal study of 913 mothers in Norway followed from when their children were 18 months old (time 1) until they were 14.5 years (time 6) (the TOPP study). Multinomial logistic regression analyses were used to test whether child related stressors, stressors related to the living conditions, social support and maternal temperament at time 1 predicted membership in groups based on maternal symptoms of depression and anxiety over the subsequent 13 years. RESULTS: Temperamental distress, followed by child related stressors, were the strongest predictors of membership in a group with high symptoms of depression and anxiety over time. Stressors related to living conditions, and social support from partner and friends/family were also significant predictors. No interaction effects among predictors were found. CONCLUSIONS: This study indicates that factors present early in the child rearing phase may provide substantial prediction of the variance in maternal symptoms of depression and anxiety over the following 13 years. Temperamental distress and child related stressors were the strongest predictors of membership in different depression and anxiety symptom trajectory groups.

Trajectories of maternal symptoms of anxiety and depression. A 13-year longitudinal study of a population-based sample.

BACKGROUND: There is a lack of population-based studies of developmental trajectories following mothers throughout the whole child-rearing phase and there are few longitudinal studies focusing on both symptoms of depression and anxiety. The aim of the current study is to identify latent trajectory groups based on counts of symptoms of anxiety and depression among mothers throughout the child-rearing phase and the relations of the latent groups to maternal socio-demographic variables. METHODS: Data is from a prospective, longitudinal study of nearly 1000 families in Norway followed from when the index children were 18 months until they were 14.5 years old (the TOPP study). The study used latent profile analysis (LPA) to identify latent groups of mothers with distinct trajectories across time of symptom counts. Latent group differences on socio-demographic variables were tested with one-way ANOVAs, chi-square tests and exact tests. RESULTS: Six trajectories based on maternal scores from six waves of data collection of symptoms of anxiety and depression were identified; a 'No symptoms' group with mothers without symptoms; a 'Low' group with mothers reporting low symptom levels; a 'Moderate-low' group with mothers reporting moderately low symptom levels; a 'Moderate' group with mothers with moderate symptoms; a 'High-chronic' group with mothers with overall high symptom levels; and a 'Low-rising' group with mothers starting with a low symptom level that increased over time. The mothers in the High-chronic symptom group differed from the other mothers on several socio-demographic variables. They were significantly younger than the mothers in the Low group comprising the oldest mothers. The mothers in the High-chronic group had significantly lower education, were less likely to have paid work and were less likely to be living with a partner than the mothers in the other groups. CONCLUSIONS: The study shows socio-demographic differences between mothers classified into six trajectory groups based on symptoms of anxiety and depression covering 13 years of the child-rearing period. Specific socio-demographic risk factors characterised mothers in the High-chronic symptom group. Identifying subgroups with enduring problems might inform more targeted preventive efforts.

Predictors and pathways from infancy to symptoms of anxiety and depression in early adolescence.

Data from a prospective 11-year longitudinal survey were used to identify early predictors and pathways to symptoms of anxiety and depression at 12-13 years of age, and to examine whether there were unique predictors of anxious versus depressive symptoms. Structural equation modeling was used to explore longitudinal relations between contextual (maternal distress, family adversities, and social support) and temperamental (shyness and emotionality) risk factors in their prediction of informant-consistent symptoms of anxiety and depression. The results show that early risk factors can explain 38% of the variance in boys' covarying symptoms of anxiety and depression in early adolescence, and 25% of variance in girls' covarying symptoms. Two main pathways were identified. One pathway was through temperament, as nearly all risk factors were partly mediated through child emotionality in midchildhood. Another pathway was through early contextual risk factors, with all direct and indirect contextual impact from before 5 years of age. Family adversity uniquely predicted depressive symptoms. These findings underscore the persisting impact of contextual predictors in families with children less than 5 years of age. The importance of early interventions to prevent adolescent internalizing problems is stressed.

Temperament profiles from infancy to middle childhood: development and associations with behavior problems.

The authors applied I-States as Objects Analysis (ISOA), a recently proposed person-oriented analytic approach, to the study of temperament development in 921 Norwegian children from a population-based sample. A 5-profile classification based on cluster analysis of standardized mother reports of activity, sociability, emotionality, and shyness at ages 18 months, 30 months, 4-5 years, and 8-9 years was interpretable and highly replicable. The prevalence of temperament profiles changed markedly with age, and individual stability in temperament profiles was significant. Specific typical and atypical developmental sequences of profiles were identified. Selective patterns of concurrent group differences in externalizing and internalizing problems by temperament profiles were remarkably similar across ages. The findings to some degree support the notion that individual temperament-variable values take on meaning in relation to the whole individual configuration and indicate some lawfulness in temperament changes over time. Future person-oriented studies of temperament development should replicate the current results using multiple data sources, rigorous tests of gender differences, and latent group modeling.

Long shadows: a prospective study of predictors of relationship dissolution over 17 child-rearing years.

BACKGROUND: Parental relationship dissolutions have repeatedly been linked to negative outcomes for children, but predictors of parental dissolutions have been far less studied. Knowledge about parental dissolutions occurring after the early years of parenthood is especially sparse. The aim of the current study was to investigate whether a broad set of predictors from families of toddlers were associated with relationship dissolutions throughout the next 17 years of parenthood. We specifically investigated whether different predictors were associated with short and long term dissolutions; and whether associations with long term dissolutions were mediated by relationship dissatisfaction or child-rearing conflicts. METHODS: Questionnaire data from 500 married or cohabiting mothers participating in a longitudinal population based study, the Norwegian TOPP study, was used. Child related strains, positive and negative aspects of relationship quality, and other intrinsic, environmental, and socio-demographic factors were assessed when children were 18 months old. Associations between early predictors and early dissolution (before children were 8 years old) and late dissolutions (when children were between 8 and 19 years) were compared using multinomial logistic regression analyses. Indirect paths from early predictors through relationship satisfaction and child-rearing conflicts to late dissolutions were investigated among couples that were still intact when children were 8 years old. RESULTS: Expression of criticism and most socio-demographic variables were associated with early dissolutions only, while temperamental sociability and child related strains were associated with long term dissolutions only in the adjusted regression models. Low levels of emotional support predicted both early and late dissolutions. Associations from low emotional support and child related strains to long term dissolutions were mediated by relationship dissatisfaction, indicating that cascades towards dissolutions may originate in these early predictors. No indirect paths were identified from early predictors through child-rearing conflicts, indicating that low levels of positivity, rather than high conflict levels, are associated with dissolutions in long-term relationships. CONCLUSIONS: Predictors of dissolutions over the next 17 years could be identified among mothers of toddlers. Different predictors were associated with early and late dissolutions, indicating different cascades.

A prospective longitudinal study of shyness from infancy to adolescence: stability, age-related changes, and prediction of socio-emotional functioning.

This longitudinal, population-based and prospective study investigated the stability, age-related changes, and socio-emotional outcomes of shyness from infancy to early adolescence. A sample of 921 children was followed from ages 1.5 to 12.5 years. Parent-reported shyness was assessed at five time points and maternal- and self-reported social skills and symptoms of anxiety and depression were assessed at age 12.5 years. Piecewise latent growth curve analysis was applied, with outcomes regressed on latent shyness intercept and slope factors. Results showed moderate stability and increasing levels of shyness across time, with more variance and a steeper increase in early as compared to mid-to-late childhood. Both stable shyness and increased shyness in mid-to-late (but not early) childhood predicted poorer social skills and higher levels of anxiety and depression symptoms in early adolescence. The implications of the evidence for two developmental periods in shyness trajectories with differential impact on later socio-emotional functioning are discussed.

Childhood predictors of recurrent abdominal pain in adolescence: A 13-year population-based prospective study.

OBJECTIVE: To investigate maternal and child emotional symptoms, physical health problems, and negative life events measured at children's age 18 months and 12 years as potential predictors for self-reported recurrent abdominal pain (RAP) in adolescents (14 years). METHODS: A population-based prospective study conducted at child health clinics (preventive health care) in Norway followed a cohort of 916 mothers with children from children's age 18 months until adolescence. Child self-report was obtained from 12 years of age. Outcome measure was adolescent self-reported RAP. RESULTS: Of 456 adolescents, 58 (13%) reported RAP. Of these, 36 (62%) were girls. By multivariate analyses, the following maternal factors predicted RAP in adolescence: psychological distress at children's age 18 months (OR, 2.5; 95% CI, 1.3-4.8) and a maternal history of psychological distress at children's age 12 years (OR, 3.2; 95% CI, 1.7-6.2). The following child factors measured at age 12 years predicted RAP in adolescence: abdominal (OR, 2.5; 95% CI, 1.3-4.9) and extraintestinal pain (OR, 2.3; 95% CI, 1.2-4.4) by maternal report, self-reported frequent extraintestinal pain (OR, 2.9; 95% CI, 1.4-5.9), and self-reported depressive symptoms (OR, 2.4; 95% CI, 1.1-5.1). Negative life events and physical health in mothers and toddlers did not predict RAP. CONCLUSIONS: This is the first cohort study that finds maternal psychological distress in early childhood to predict RAP in their offspring 13 years later. Our results support that maternal psychological distress and preadolescent children's depressive and somatic symptoms may play a role in the development of RAP.

The nature and predictors of undercontrolled and internalizing problem trajectories across early childhood.

Using growth curve modeling, trajectories of undercontrolled (oppositional, irritable, inattentive and overactive behaviors) and internalizing (worried, sad and fearful) problems from 18 months to 4.5 years were studied in a population based sample of 921 Norwegian children. At the population level, undercontrolled problems decreased and internalizing problems increased with increasing age. Child temperament and family factors present at 18 months predicted 43% of the stability and 20% of the linear changes in undercontrolled problems and 30% of the stability and 7% of the linear changes in internalizing problems. Persisting effects of child and family factors from 18 month were found on the two problem dimensions over and above the impact of changes in the same risk factors. Lower initial level of partner support and higher initial level of child emotionality predicted higher slope of undercontrolled problems and higher initial level of family stress predicted higher slope for internalizing problems. As expected, time to time change (t1 to t2 and t2 to t3) in risk factors predicted time to time change in problem scores as well. The study shows the significance of early emerging internalizing and undercontrolled problems, the need to consider their pathways separately from very young ages, lasting effects of early experiences, and the importance of a dynamic approach to the analysis of risk.

The Strengths and Difficulties Questionnaire in the Nordic countries.

BACKGROUND: The Strengths and Difficulties Questionnaire (SDQ) has been translated into the different Nordic languages between 1996 and 2003. During the past few years, SDQs have been completed for nearly 100,000 children and adolescents in population-based studies as well as in clinical samples. The largest studies have been performed in Norway and Denmark, and in these countries the diagnostic interview DAWBA has also been used in conjunction with the SDQ. AIMS: In addition to a brief overview of past and ongoing SDQ work in Sweden, Finland, Norway, Denmark, and Iceland, we present scale means and standard deviations from selected community studies with comparable age groups, including parental reports for 7, 9 and 11 year-old children and self-reports of 13 and 15 year-olds. CONCLUSIONS: The descriptive statistics suggest that the distributions of SDQ scores are very similar across the Nordic countries. Further collaborative efforts in establishing norms and evaluating the validity of the SDQ as a screening instrument are encouraged.
