Medication adherence in psychopharmacologically treated adults with ADHD.

OBJECTIVE: One of the potential causes of residual symptoms of ADHD in adults can be difficulties with consistent adherence to medications. METHOD: This formative study examined self-reported medication adherence in adults with ADHD with clinically significant symptoms despite medication treatment. RESULTS: Mean adherence for the two-week period prior to the assessment point was 86%, with 18% of the sample reporting less than 80% adherence, and 43% less than 90% adherence. Adherence correlated with ADHD symptoms but not anxiety or depression. Those with less than 80% adherence had higher ADHD severity compared to those whose adherence was at least 80%. CONCLUSION: These data suggest that self-report of adherence to ADHD medications may be a useful and expedient way of assessing adherence, and that assessment and counseling about adherence may be an important part of treatment. Future research using an objective indicator of adherence is needed to follow up on these findings.

The prospective impact of sleep duration on depression and mania.

OBJECTIVE: Many patients report sleeping less than 6 h per night during episodes of depression and mania. This type of sleep deficit may also be a risk factor for subsequent mood episodes; however, the long-term impact of sleep deficit remains unclear. The current study is among few longitudinal studies to assess the prospective effect of sleep deficit on depression and mania. METHODS: A subsample of 54 individuals from a longitudinal study of bipolar I disorder was selected. Participants entered the study during a mood episode. Baseline symptom data were collected at month 4 to allow for recovery from the initial episode, sleep was assessed at month 6, and follow-up symptom data were obtained during months 7-12. RESULTS: Sleep deficit predicted depressive symptoms across the 6-month follow-up but not mania. CONCLUSIONS: It is likely that the impact of sleep deficit on mania was probably missed because assessments covered a full month. Monitoring sleep duration may help predict depression in bipolar disorder and provide an opportunity for targeting intervention.

Clinical characteristics of adults reporting repressed, recovered, or continuous memories of childhood sexual abuse.

The authors assessed women and men who either reported continuous memories of their childhood sexual abuse (CSA, n = 92), reported recovering memories of CSA (n = 38), reported believing they harbored repressed memories of CSA (n = 42), or reported never having been sexually abused (n = 36). Men and women were indistinguishable on all clinical and psychometric measures. The 3 groups that reported abuse scored similarly on measures of anxiety, depression, dissociation, and absorption. These groups also scored higher than the control group. Inconsistent with betrayal trauma theory, recovered memory participants were not more likely to report abuse by a parent or stepparent than were continuous memory participants. Rates of depression and posttraumatic stress disorder did not differ between the continuous and recovered memory groups.

Autobiographical memory specificity in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse.

Some psychotherapists believe that adult survivors of childhood sexual abuse (CSA) are characterised by memory deficits for their childhood. Using the Autobiographical Memory Test (AMT), we asked nonabused control participants and participants who reported either continuous, recovered, or repressed memories of CSA to retrieve a specific personal memory in response to either positive or negative cue words from either childhood or adolescence/adulthood. The results indicated that participants who believed they harboured repressed memories of abuse tended to exhibit the greatest difficulty retrieving specific memories from their childhood. Neither posttraumatic stress disorder (PTSD) nor major depression was related to diminished memory specificity.

Complicated grief and its correlates in patients with bipolar disorder.

BACKGROUND: While the recent loss of a loved one has been identified as a risk factor for suicide in patients with bipolar disorder, and complicated grief (CG) has been associated with elevated rates of suicidality compared with loss without CG, little is known about the frequency or impact of CG in bipolar disorder. We investigated the frequency and implications of loss of loved ones in an ongoing study of bipolar disorder. METHOD: We conducted a survey of 120 patients with well-characterized DSM-IV bipolar disorder participating in Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), a large naturalistic study, in order to identify frequency of loss and to examine the presence of CG and its clinical correlates. Survey data were gathered from October 2003 to March 2004. RESULTS: A lifetime history of a significant loss was reported by 86% (103/120) of participants; 24.3% (25/103) of those met criteria for CG, defined as a score > or = 25 on the Inventory of Complicated Grief (ICG), with a mean +/- SD ICG score of 33.7 +/- 6.9. The presence of CG was associated with elevated rates of panic disorder and alcohol abuse comorbidity, as well as other measures of panic symptoms and phobic avoidance. CG was also associated with a higher rate of lifetime suicide attempts, greater functional impairment, and poorer social support. CONCLUSION: Our findings suggest the presence of a substantial burden of comorbid grief-related illness and impairment in patients with bipolar disorder. Further research is needed to understand the overlap of anxiety disorders and phobic avoidance in bipolar patients with complicated grief.

Forgetting of trauma cues in adults reporting continuous or recovered memories of childhood sexual abuse.

According to betrayal trauma theory, adult survivors of childhood sexual abuse (CSA) who were molested by their caretakers (e.g., a father) are especially likely to dissociate ("repress") their memories of abuse. Testing college students, some reporting CSA, DePrince and Freyd (2004) found that those scoring high on a dissociation questionnaire exhibited memory deficits for trauma words when they viewed these words under divided-attention conditions. Replicating DePrince and Freyd's procedure, we tested for memory deficits for trauma words relative to neutral words in adults reporting either continuous or recovered memories of CSA versus adults denying a history of CSA. A memory deficit for trauma words under divided attention was expected in the recovered-memory group. Results were inconsistent with this prediction, as all three groups exhibited better recall of trauma words than neutral words, irrespective of encoding conditions.

Posttraumatic stress disorder in patients with bipolar disorder: a review of prevalence, correlates, and treatment strategies.

OBJECTIVES: In this article, we review the evidence for, and implications of, a high rate of comorbid posttraumatic stress disorder (PTSD) in individuals with bipolar disorder. METHODS: We reviewed studies providing comorbidity data on patients with bipolar disorder, and also examined the PTSD literature for risk factors and empirically supported treatment options for PTSD. RESULTS: Studies of bipolar patients have documented elevated rates of PTSD. Based on our review, representing 1214 bipolar patients, the mean prevalence of PTSD in bipolar patients is 16.0% (95% CI: 14-18%), a rate that is roughly double the lifetime prevalence for PTSD in the general population. Risk factors for PTSD that are also characteristic of bipolar samples include the presence of multiple axis I disorders, greater trauma exposure, elevated neuroticism and lower extraversion, and lower social support and socio-economic status. CONCLUSIONS: These findings are discussed in relation to the cost of PTSD symptoms to the course of bipolar disorder. Pharmacological and cognitive-behavioral treatment options are reviewed, with discussion of modifications to current cognitive-behavioral protocols for addressing PTSD in individuals at risk for mood episodes.
