The Bi-Directional Relationship Between Parent–Child Conflict and Treatment Outcome in Treatment-Resistant Adolescent Depression

Objective

To examine the bidirectional relationship between parent–child discord and treatment outcome for adolescent treatment-resistant depression.

Method

Depressed youth who had not responded to an adequate course of a selective serotonin reuptake inhibitor (SSRI) were randomized to either a switch to another SSRI or venlafaxine, with or without the addition of cognitive behavior therapy (CBT) in the Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) study. The Conflict Behavior Questionnaire was used to assess adolescent (CBQ-A) and parent-reported (CBQ-P) parent–child discord. The impact of remission on parent–child conflict, and the differential impact of medication and CBT on the CBQ-A and CBQ-P, were assessed using generalized linear models.

Results

Although there were no differential treatment effects on parent or adolescent-report of conflict, remission was associated with improvement in the CBQ-P. In general, intake family conflict did not predict remission, except in the sub-group of participants whose parents reported clinically significant parent–child conflict at intake, for whom high levels of parent-reported conflict predicted a lower likelihood of remission. Conflict also did not moderate treatment response.

Conclusions

Remission of depression may be sufficient to reduce parent-reported parent–child conflict. However, higher parent-reported conflict, in the clinically significant range, predicts a lower likelihood of remission from depression.

Participants

Participants consisted of 334 adolescents between 12 and 18 years of age enrolled in the Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) study. The participants had to have a clinical diagnosis of major depressive disorder (MDD) or dysthymia by DSM-IV criteria,27 moderate-to-severe depressive symptoms, (≥40 on the Children’s Depression Rating Scale–Revised [CDRS-R],28 and ≥4 on the Clinical Global Impression–Severity Subscale [CGI-S]28, 29) which persisted despite an 8-week trial

Range and Correlates of the CBQ

At entry, participants’ scores on the CBQ-A ranged from 0 to 20 (mean = 8.92, standard deviation [SD] = 6.21), with 50.5% in the clinically significant range (≥9). The CBQ-A was positively correlated with a number of indicators of clinical severity, including global severity (CGI-S), depression (CDRS-R, BDI), hopelessness (BHS), self-harm (SIQ, past attempt, non-suicidal self-harm), and comorbid conditions (alcohol/drug use, disruptive behavior disorders) (TABLE 1, TABLE 2). Of these, only the

Discussion

In this article, we have examined the extent to which adolescent and parent-reported parent–child conflict predicted or moderated treatment response and, conversely, the degree to which treatments for depression affected parent–child conflict. We found that treatment effects were relatively unaffected by parent–child conflict, as reported by either parent or adolescent. Adolescent-reported parent–child conflict at baseline did predict a lower likelihood of remission, but not after controlling

      The effectiveness of SSRIs varies across individuals, but no validated markers exist to inform clinical decision making. A number of potential moderating factors have been investigated in adolescents, including specific symptoms,96,109,110 symptom severity,32,34,111–119 abuse or trauma history,120,121 genetic polymorphisms,53,122–127 neural structure and response,86,128–132 family,102–104,117,119 and demographic characteristics.32,34,116,119,133 However, studies have typically been small in scale and have not focused on whether these factors are general markers of outcome or specific to SSRI treatment.

      Specifically, perceived intrafamilial relationships bear consequence on adolescents’ mental well-being, as negative relationships with one or both parents, and a negative rapport between parents have been shown to be associated with a higher risk for suicide and/or depression among adolescents (Consoli et al., 2013). What's more, higher parent-reported conflict was found to predict a lower likelihood of remission among adolescents with treatment resistant depression (Rengasamy et al., 2013). Across age groups, those with clinically significant depressive symptoms were also more likely to have a lower parental GHQ scores, indicating poor parental mental health.
