OBJECTIVE: To investigate whether the change in dysfunctional posttraumatic cognitions (PTC) during Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) is a mediator of posttraumatic stress symptom (PTSS) reduction in a sample of children and adolescents. METHOD: A bootstrap mediation analysis was performed to investigate the indirect effect of dysfunctional PTC on treatment outcome in a recently completed RCT study with children and adolescents (n = 123; 7-17 years old) that investigated the effectiveness of TF-CBT...

Previous studies have suggested that children with Attention-Deficit/Hyperactivity Disorder (ADHD) may benefit less from behavioral parent training (BPT) if their parents have high levels of ADHD symptoms. We conducted a secondary analysis of data from a randomized controlled trial to test the hypothesis that parental ADHD symptoms reduce the efficacy of two BPT programs in a sample of preschoolers with ADHD. One intervention was specifically designed for children with ADHD (NFPP: New Forest Parenting Programme) and one was designed for children with Oppositional Defiant Disorder (ODD) (HNC: Helping the Noncompliant Child)...

Anhedonia-defined as loss of interest or pleasure-is one of two core symptoms of major depressive disorder (MDD). Anhedonia may involve decreased enjoyment of potentially rewarding activities and decreased motivation to engage in such activities. Increased engagement with reinforcers-activities with the potential to be positive experiences-is a frequent target of cognitive-behavioral therapies. Nevertheless, how environmental reinforcers are perceived, and how decisions to approach or avoid them are made by individuals with MDD, is largely unknown...

Recent research has highlighted the etiological role of sleep disturbance in posttraumatic stress disorder (PTSD); however it is currently unknown how daily changes in sleep are associated with next-day PTSD symptoms. Furthermore, sleep is critical for maintaining appropriate affect, leading some to hypothesize that affective dysfunction may account for the link between sleep disturbances and PTSD symptoms. Thus, the current study tested the relationship between sleep disturbances, affective valence, and PTSD symptoms utilizing an ecological momentary assessment (EMA) design among individuals with PTSD (n=30) who participated in 4 EMA-based assessments daily over 8 days...

BACKGROUND: Internet interventions are effective in treating depressive symptoms but few studies conducted a long-term follow-up. The aim of this study was to test the effectiveness of an internet intervention in increasing the remission rate over a twelve months period. METHODS: A total of 1013 participants with mild to moderate depressive symptoms were randomized to either care as usual alone or a 12-week internet intervention (Deprexis) plus usual care. Self-rated depression severity (PHQ-9) was assessed regularly over twelve months...

BACKGROUND: Auditory Hallucinations may arise from people confusing their own inner speech with external spoken speech. People with visual hallucinations (VH) may similarly confuse vivid mental imagery with external events. This paper reports two experiments exploring confusion between internal and external visual material. METHOD: Experiment 1 examined reality monitoring in people with psychosis; those with visual hallucinations (n = 16) and those without (n = 15)...

The neural mechanism underlying attentional bias in OCD (Obsessive-Compulsive Disorder) remains unclear. The goal of this study was to examine and compare the time course and the event related potential (ERP) components in OCD patients and healthy controls (HC) to reveal the complex brain activation pattern associated with attentional bias in OCD. The behavioural and electroencephalogram (EEG) data were recorded while the participants performed an emotional Stroop task. Compared to HC, the individuals with OCD exhibited slower response time, prolonged N1 latency and larger N1 and P2 amplitudes across different emotional words...

This study tested the hypotheses that borderline personality (BP) features are characterized by a negativity bias and instability in spontaneous and deliberate evaluations of others. Undergraduate women (N = 204) watched two movie clips depicting either positive or negative conjugal interactions. Spontaneous and deliberate evaluations of the male character were assessed after each clip with an Evaluative Priming Task and a self-report measure, respectively. Participants with high BP features showed unstable spontaneous evaluations...

Anxiety disorders are among the most common disorders affecting youths in the general population, with up to 10% of children and 20% of adolescents meeting criteria for an anxiety disorder at any one point in time. Cognitive-behavior therapies (CBT), varying between 9 and 18 weeks of treatment, are considered evidence-based for the treatment of anxiety disorders in youth. During the last two decades treatments that are brief, intensive, or concentrated (BIC) have been developed and this meta-analysis includes 23 RCTs of these new approaches across the anxiety disorders...

Depression often is characterized by inflexible autonomic and metacognitive processes that interfere with effective self-regulation. However, few studies have integrated these factors to improve the prediction of which individuals are at greatest risk for depression. Among 134 undergraduates, we evaluated whether parasympathetic inflexibility (a lack of reduction in respiratory sinus arrhythmia) in response to a sadness induction involving loss would prospectively predict symptoms of depression across four waves of follow-up over twelve weeks...

Rumination is a well-established vulnerability factor for depression that may exert deleterious effects both independently and in interaction with stress. The current study examined momentary ruminative self-focus (MRS) and stress-reactive rumination (SRR) as predictors of depressive symptoms utilizing a smartphone ecological momentary assessment (EMA) design. 121 undergraduates responded to four text message alerts per day for one week in which they indicated the occurrence of life stress, rumination, and depressed mood...

The effectiveness and mechanisms of psychotherapies for posttraumatic stress disorder (PTSD) in treating sleep problems is of interest. This study compared the effects of a trauma-focused and a non-trauma-focused psychotherapy on sleep, to investigate whether 1) sleep improves with psychotherapy for PTSD; 2) the degree of sleep improvement depends on whether the intervention is trauma or nontrauma-focused; 3) the memory-updating procedure in cognitive therapy for PTSD (CT-PTSD) is associated with sleep improvements; 4) initial sleep duration affects PTSD treatment outcome; and 5) which symptom changes are associated with sleep duration improvements...

Extinction memories are fragile and their formation has been proposed to partially rely on vagus nerve activity. We tested whether stimulating the auricular branch of the vagus (transcutaneous VNS; tVNS) accelerates extinction and reduces spontaneous recovery of fear. Forty-two healthy students participated in a 3-day fear conditioning study, where we tested fear acquisition (day 1), fear extinction (day 2) and the retention of the extinction memory (day 3). During extinction, participants were randomly allocated to receive tVNS or sham stimulation concurrently with each CS presentation...

Impulsivity is a core characteristic of externalizing problems and a robust predictor of alcohol use in adolescence. There is little evidence on the causal mechanisms through which impulsivity influences drinking or how they are affected by key social factors (peer influence). This study reports the development of the first comprehensive laboratory model of adolescent impulsivity and alcohol use. One-hundred and twenty adolescents (50% female) of legal drinking age (M = 19.47 years, SD = 1.12) in Australia (18+ years) were subjected to 1 of 3 experimental manipulations to increase impulsive behavior (reward cue exposure, negative mood induction, ego depletion)...

Borderline personality disorder (BPD) is a severe mental condition characterized by a range of cognitive and behavioral vulnerabilities, including chronic shame and deficits in social problem solving (SPS) abilities. Little research however, has examined strategies that may alleviate shame and SPS deficits among individuals with BPD traits. Using a laboratory experimental approach, the present study compared the effects of a brief mindfulness versus loving-kindness meditation (LKM) induction on shame and SPS abilities in a sample of adults with high BPD traits...

Interventions involving rescripting-based imagery have been proposed as a better approach than exposure-based imagery when posttraumatic stress disorder (PTSD) is associated with emotions other than fear. Prior research led to the study's hypotheses that (a) higher pretreatment non-fear emotions would predict relatively better response to rescripting as compared to exposure, (b) rescripting would be associated with greater reduction in non-fear emotions, and (c) pretreatment non-fear emotions would predict poor response to exposure...

Repetitive negative thinking and perfectionism have both been proposed as processes that are related to depressive symptoms. The purpose of this study was to investigate concurrent and prospective relationships between antenatal and postnatal depression, perfectionism, and repetitive negative thinking. A longitudinal design was used and 71 women were followed from their third trimester of pregnancy to six weeks post birth. A structural equation model was tested with antenatal perfectionism predicting antenatal repetitive negative thinking, perfectionism predicting postnatal depression, and antenatal repetitive negative thinking predicting antenatal and postnatal depression...

Nightmares can be effectively treated with cognitive-behavioral therapies. Though it remains elusive which therapeutic elements are responsible for the beneficial effects on nightmare symptoms, imagery rescripting (IR) and imaginal exposure (IE) are commonly identified as active treatment components of nightmare therapies. With this randomized controlled trial, we compared IR and IE as individual treatments to a wait-list (WL) condition to determine whether these particular therapeutic elements ameliorate nightmare symptoms...

Cognitive-Behavioral Group Therapy (CBGT) and Mindfulness-Based Stress Reduction (MBSR) are efficacious in treating social anxiety disorder (SAD). It is not yet clear, however, whether they share similar trajectories of change and underlying mechanisms in the context of SAD. This randomized controlled study of 108 unmedicated adults with generalized SAD investigated the impact of CBGT vs. MBSR on trajectories of social anxiety, cognitive reappraisal, and mindfulness during 12 weeks of treatment. CBGT and MBSR produced similar trajectories showing decreases in social anxiety and increases in reappraisal (changing the way of thinking) and mindfulness (mindful attitude)...
