Family Support and Conflict: Prospective Relations to Adolescent Depression

The relations between family support, family conflict, and adolescent depressive symptomatology were examined longitudinally in a sample of 231 female and 189 male adolescents and their mothers. Structural equation models revealed that less supportive and more con-flictual family environments were associated with greater depressive symptomatology both concurrently and prospectively over a 1-year period. Conversely, adolescent depressive symptomatology did not predict deterioration in family relationships. Depressive symptomatology and, to a greater extent, family characteristics showed high levels of stability over the 1-year period. Counter to our expectations, the relations between family variables and depressive symptomatology were similar for boys and girls. The results suggest that the quality of family interactions is relevant for understanding the development of depressive symptoms in adolescents.

Adolescents' relationships with their mothers and fathers : Associations with depressive disorder and subdiagnostic symptomatology

Family relationships across 3 groups of adolescents were compared: (a) those with unipolar depressive disorders (n=82); (b) those with subdiagnostic depressive symptoms (n=78); and (c) those without emotional or behavioral difficulties (n=83). Results based on multisource, multimethod constructs indicated that depressed adolescents, as well as those with subdiagnostic symptomatology, experience less supportive and more conflictual relationships with each of their parents than do healthy adolescents. These findings are notable in demonstrating that adverse father-adolescent relationships are associated with depressive symptomatology in much the same way as mother-adolescent relationships. As well, the findings add to the emerging evidence that adolescents with subdiagnostic symptoms experience difficulties in social relationships similar to those experienced by adolescents with depressive disorder.

Emotional Inertia and Psychological Maladjustment

In this article, we examine the concept of emotional inertia as a fundamental property of the emotion dynamics that characterize psychological maladjustment. Emotional inertia refers to the degree to which emotional states are resistant to change. Because psychological maladjustment has been associated with both emotional underreactivity and ineffective emotion-regulation skills, we hypothesized that its overall emotion dynamics would be characterized by high levels of inertia. We provide evidence from two naturalistic studies that, using different methods, showed that the emotional fluctuations of individuals who exhibited low self-esteem (Study 1) and depression (Study 2) were characterized by higher levels of inertia in both positive and negative emotions than the emotional fluctuations of people who did not exhibit low self-esteem and depression. We also discuss the usefulness of the concept of emotional inertia as a hallmark of maladaptive emotion dynamics.

School-Based Primary Prevention of Depressive Symptomatology in Adolescents Findings from Two Studies

Two school-based primary prevention interventions for adolescent depressive symptomatology and disorder were examined in separate studies with high school samples of 9th and 10th-grade adolescents. In Study 1, a three-session educational intervention was associated with a short-term reduction in extreme-scoring cases of depressive symptoms among boys, but not girls, when compared to a randomly assigned control condition. However, this effect was not sustained over a 12-week follow-up period. In Study 2, a five-session behavioral skills training intervention, failed to demonstrate any differences compared to a random control condition. Neither of the two interventions had any effect on depression knowledge, attitudes toward treatment, or actual treatment seeking. The failure of these interventions to yield long-term effects is discussed in the context of successful prevention interventions for nonneurotic problem behaviors. The authors conclude that depression may be best prevented with a competency-based intervention targeting several disorders.

Child responses to parental conflict and their effect on adjustment: A study of triadic relations.

The purpose of this study was to examine child response patterns to parental conflict and assess their contribution to child functioning. The focus was on 3 potential child responses and their relation to later depressive and aggressive behavior. Direct observations and questionnaire data were collected on 156 2-parent families. Aggressive behavior showed the strongest sequential relation to interparental conflict and the strongest predictive relation to increased aggressive functioning. Gender differences were found in the use of child aggressive response patterns. Results for the relation between child responses and increases in depressive functioning were weaker than those found for aggressive functioning. The results provide support fpr the examination of child response patterns as a potentially rich area of exploration for understanding the family mechanisms affecting both aggressive and depressive functioning in children.

Emotional inertia prospectively predicts the onset of depressive disorder in adolescence.

Emotional inertia refers to the degree to which a persons current emotional state is predicted by their prior emotional state, reflecting how much it carries over from one moment to the next. Recently, in a cross-sectional study, we showed that high inertia is an important characteristic of the emotion dynamics observed in psychological maladjustment such as depression. In the present study, we examined whether emotional inertia prospectively predicts the onset of first-episode depression during adolescence. Emotional inertia was assessed in a sample of early adolescents (N = 165) based on second-to-second behavioral coding of videotaped naturalistic interactions with a parent. Greater inertia of both negative and positive emotional behaviors predicted the emergence of clinical depression 2.5 years later. The implications of these findings for the understanding of the etiology and early detection of depression are discussed.

Parental Behaviors During Family Interactions Predict Changes in Depression and Anxiety Symptoms During Adolescence

This study investigated the prospective, longitudinal relations between parental behaviors observed during parent-adolescent interactions, and the development of depression and anxiety symptoms in a community-based sample of 194 adolescents. Positive and negative parental behaviors were examined, with negative behaviors operationalized to distinguish between observed parental expressions of aggression and dysphoria. Results showed that higher levels of parental aggression prospectively predicted higher levels of both depression and anxiety symptoms in adolescents over two-and-a-half years, whereas higher levels of positive parental behaviors prospectively predicted lower levels of depression symptoms only. Parental dysphoric behavior was not related to changes in either symptom dimension. These results suggest that patterns of parental behaviors may be differentially associated with depressive versus anxious outcomes in adolescents, and highlight the potential role for family-focused prevention or treatment interventions aimed at reducing an escalation of depression and anxiety symptoms in adolescence.

Interactional processes in families with depressed and non-depressed adolescents: reinforcement of depressive behavior

Problem-solving interactions were observed in 86 families of depressed adolescents and 408 families of non-depressed adolescents. Sequential analyses indicated that mothers of depressed adolescents were more likely than mothers of non-depressed adolescents to increase facilitative behavior in response to adolescent depressive behavior. Additionally, fathers of depressed adolescents were more likely than their counterparts in families of non-depressed adolescents to decrease aggressive behavior subsequent to adolescent depressive behavior. These analyses suggest that parents of depressed adolescents may be inadvertently reinforcing depressive behavior. Decreases in adolescent depressive symptomatology from year 1 to year 2 were not accompanied by changes in family interaction patterns.

Positive parenting predicts the development of adolescent brain structure: a longitudinal study.

Highlights • Positive parenting predicts development of adolescent amygdala and prefrontal cortex.• Positive parenting has a unique influence on adolescent brain development.• Positive and negative parenting are not opposite sides of a continuum.• Parenting interventions may promote healthy adolescent brain development.

Getting stuck in depression: The roles of rumination and emotional inertia

Like many other mental disorders, depression is characterised by psychological inflexibility. Two instances of such inflexibility are rumination: repetitive cognitions focusing on the causes and consequences of depressive symptoms; and emotional inertia: the tendency for affective states to be resistant to change. In two studies, we tested the predictions that: (1) rumination and emotional inertia are related; and (2) both independently contribute to depressive symptoms. We examined emotional inertia of subjective affective experiences in daily life among a sample of non-clinical undergraduates (Study 1), and of affective behaviours during a family interaction task in a sample of clinically depressed and non-depressed adolescents (Study 2), and related it to self-reported rumination and depression severity. In both studies, rumination (particularly the brooding facet) and emotional inertia (particularly of sad/dysphoric affect) were positively associated, and both independently predicted depression severity. These findings demonstrate the importance of studying both cognitive and affective inflexibility in depression.
