Different learning aberrations relate to delusion-like beliefs with different contents.

The prediction error account of delusions has had success. However, its explanation of delusions with different contents has been lacking. Persecutory delusions and paranoia are the common unfounded beliefs that others have harmful intentions towards us. Other delusions include believing that one's thoughts or actions are under external control, or that events in the world have specific personal meaning. We compare learning on two different cognitive tasks, probabilistic reversal learning (PRL) and Kamin blocking, that have relationships to paranoid and non-paranoid delusion-like beliefs, respectively. We find that Clinical High-Risk status alone does not result in different behavioral results on the PRL task but that an individual's level of paranoia is associated with excessive switching behavior. During the Kamin blocking task, paranoid individuals learned inappropriately about the blocked cue. However, they also had decreased learning about the control cue, suggesting more general learning impairments. Non-paranoid delusion-like belief conviction (but not paranoia) was associated with aberrant learning about the blocked cue but intact learning about the control cue, suggesting specific impairments in learning related to cue combination. We fit task-specific computational models separately to behavioral data to explore how latent parameters vary within individuals between tasks, and how they can explain symptom-specific effects. We find that paranoia is associated with low learning rates on the PRL task as well as the blocking task. Non-paranoid delusion-like belief conviction was instead related to parameters controlling the degree and direction of similarity between cue updating during simultaneous cue presentation. These results suggest that paranoia and other delusion-like beliefs involve dissociable deficits in learning and belief updating, which - given the transdiagnostic status of paranoia - may have differential utility in predicting psychosis.

Major stress in early childhood strengthens the association between peripheral inflammatory activity and corticostriatal responsivity to reward.

BACKGROUND: Severe, chronic stress during childhood accentuates vulnerability to mental and physical health problems across the lifespan. To explain this phenomenon, the neuroimmune network hypothesis proposes that childhood stressors amplify signaling between peripheral inflammatory cells and developing brain circuits that support processing of rewards and threats. Here, we conducted a preliminary test of the basic premises of this hypothesis. METHODS: 180 adolescents (mean age = 19.1 years; 68.9 % female) with diverse racial and ethnic identities (56.1 % White; 28.3 % Hispanic; 26.1 % Asian) participated. The Childhood Trauma Interview was administered to quantify early adversity. Five inflammatory biomarkers were assayed in antecubital blood - C-reactive protein, tumor necrosis factor-a, and interleukins-6, -8, and -10 - and were averaged to form a composite score. Participants also completed a functional MRI task to measure corticostriatal responsivity to the anticipation and acquisition of monetary rewards. RESULTS: Stress exposure and corticostriatal responsivity interacted statistically to predict the inflammation composite. Among participants who experienced major stressors in the first decade of life, higher inflammatory activity covaried with lower corticostriatal responsivity during acquisition of monetary rewards. This relationship was specific to participants who experienced major stress in early childhood, implying a sensitive period for exposure, and were evident in both the orbitofrontal cortex and the ventral striatum, suggesting the broad involvement of corticostriatal regions. The findings were independent of participants' age, sex, racial and ethnic identity, family income, and depressive symptoms. CONCLUSIONS: Collectively, the results are consistent with hypotheses suggesting that major stress in childhood alters brain-immune signaling.

Sensitivity to change of the Systemic Therapy Inventory of Change (STIC) intersession scales.

Objective: The Systemic Therapy Inventory of Change (STIC) is a systemic measurement feedback system that provides therapists with feedback regarding the multidimensional clinical change in individual, couple, and family therapy. The STIC Intersession scales include Individual Problems and Strengths (IPS), Relationship with Partner (RWP), Family/Household (FH), and Child Problems and Strengths (CPS). They are administered to clients before each therapy session. The purpose of the current study is to investigate the STIC Intersession scales' sensitivity to change, the ability to detect reliable and valid changes that occur after an intervention. Method: Participants (N = 583) who voluntarily received individual, couple, or family therapy services in a randomized clinical trial attended the study. Results: By comparing the changes in pre-therapy and post-therapy scores of the STIC Intersession scales with those of the corresponding reference measures, the external sensitivity to change of the STIC Intersession scales was supported. The IPS Intersession scale showed greater change than the Beck Anxiety Inventory. However, no evidence supported the discriminant validity of CPS's change scores. Conclusion: Thus, the STIC Intersession IPS, RWP, and FH can be validly used to assess multi-systemic changes in both research and clinical work.

The reliability and validity of the revised Green et al. paranoid thoughts scale in individuals at clinical high-risk for psychosis.

INTRODUCTION: Paranoia is a common and impairing psychosis symptom, which exists along a severity continuum that extends into the general population. Individuals at clinical high-risk for psychosis (CHR) frequently experience paranoia and this may elevate their risk for developing full psychosis. Nonetheless, limited work has examined the efficient measurement of paranoia in CHR individuals. The present study aimed to validate an often-used self-report measure, the revised green paranoid thoughts scale (RGPTS), in this critical population. METHOD: Participants were CHR individuals (n = 103), mixed clinical controls (n = 80), and healthy controls (n = 71) who completed self-report and interview measures. Confirmatory factor analysis (CFA), psychometric indices, group differences, and relations to external measures were used to evaluate the reliability and validity of the RGPTS. RESULTS: CFA replicated a two-factor structure for the RGPTS and the associated reference and persecution scales were reliable. CHR individuals scored significantly higher on both reference and persecution, relative to both healthy (ds = 1.03, 0.86) and clinical controls (ds = 0.64, 0.73). In CHR participants, correlations between reference and persecution and external measures were smaller than expected, though showed evidence of discriminant validity (e.g., interviewer-rated paranoia, r = 0.24). When examined in the full sample, correlation magnitude was larger and follow-up analyses indicated that reference related most specifically to paranoia (ß = 0.32), whereas persecution uniquely related to poor social functioning (ß = -0.29). CONCLUSION: These results demonstrate the reliability and validity of the RGPTS, though its scales related more weakly to severity in CHR individuals. The RGPTS may be useful in future work aiming to develop symptom-specific models of emerging paranoia in CHR individuals.

Experiences of adversity in childhood and adolescence and cortisol in late adolescence.

Early life adversity influences the diurnal cortisol rhythm, yet the relative influence of different characteristics of adversity remains unknown. In this study, we examine how developmental timing (childhood vs. adolescence), severity (major vs. minor), and domain of early life adversity relate to diurnal cortisol rhythms in late adolescence. We assessed adversity retrospectively in early adulthood in a subsample of 236 participants from a longitudinal study of a diverse community sample of suburban adolescents oversampled for high neuroticism. We used multilevel modeling to assess associations between our adversity measures and the diurnal cortisol rhythm (waking and bedtime cortisol, awakening response, slope, and average cortisol). Major childhood adversities were associated with flatter daily slope, and minor adolescent adversities were associated with greater average daily cortisol. Examining domains of childhood adversities, major neglect and sexual abuse were associated with flatter slope and lower waking cortisol, with sexual abuse also associated with higher cortisol awakening response. Major physical abuse was associated with higher waking cortisol. Among adolescent adversities domains, minor neglect, emotional abuse, and witnessing violence were associated with greater average cortisol. These results suggest severity, developmental timing, and domain of adversity influence the association of early life adversity with stress response system functioning.

Individual differences in threat and reward neural circuitry activation: Testing dimensional models of early adversity, anxiety and depression.

Altered functioning of the brain's threat and reward circuitry has been linked to early life adversity and to symptoms of anxiety and depression. To date, however, these relationships have been studied largely in isolation and in categorical-based approaches. It is unclear to what extent early life adversity and psychopathology have unique effects on brain functioning during threat and reward processing. We examined functional brain activity during a face processing task in threat (amygdala and ventromedial prefrontal cortex) and reward (ventral striatum and orbitofrontal cortex) regions of interest among a sample (N = 103) of young adults (aged 18-19 years) in relation to dimensional measures of early life adversity and symptoms of anxiety and depression. Results demonstrated a significant association between higher scores on the deprivation adversity dimension and greater activation of reward neural circuitry during viewing of happy faces, with the largest effect sizes observed in the orbitofrontal cortex. We found no significant associations between the threat adversity dimension, or symptom dimensions of anxiety and depression, and neural activation in threat or reward circuitries. These results lend partial support to theories of adversity-related alterations in neural activation and highlight the importance of testing dimensional models of adversity and psychopathology in large sample sizes to further our understanding of the biological processes implicated.

A Current Learning Theory Approach to the Etiology and Course of Anxiety and Related Disorders.

The authors describe how contemporary learning theory and research provide the basis for models of the etiology and maintenance of anxiety and related disorders. They argue that contemporary learning theory accounts for much of the complexity associated with individual differences in the development and course of these disorders. These insights from modern research on learning overcome the limitations of earlier behavioral approaches, which were overly simplistic and have been justifiably criticized. The authors show how considerations of early learning histories and temperamental vulnerabilities affect the short- and long-term likelihood that experiences with stressful events will lead to the development of anxiety disorders. They also discuss how contextual variables during and after stressful learning experiences influence the maintenance of anxiety disorder symptoms. Thus, contemporary learning models provide a rich and nuanced understanding of the etiology and course of anxiety and related disorders.

Changes in Commitment and Sexual Satisfaction: Trajectories in Couple Therapy.

The purpose of this study was to examine the covarying relationship between commitment and sexual satisfaction in committed relationships throughout the course of couple therapy. A sample of 366 heterosexual couples completed questionnaires regarding sexual satisfaction and commitment at each of the first five sessions of couple therapy. Cross-lagged panel analyses revealed that, between the first and second therapy sessions, there was a bidirectional relationship between commitment and sexual satisfaction, with each variable at the first session predicting the other at the second session. In addition, sexual satisfaction at the second session predicted commitment at the third session.

How do worry and clinical status impact working memory performance? An experimental investigation.

BACKGROUND: Previous research has suggested that worry is negatively associated with working memory performance. However, it is unclear whether these findings would replicate across different worry levels and in individuals with anxiety and depressive disorders (i.e. clinical statuses). METHOD: One-hundred-thirty-eight participants performed a two-block working memory task (150 trials per block). Based on participants` current clinical status, four groups were considered (generalised anxiety disorder group: n = 36; clinical group with another anxiety or mood disorders: n = 33; subclinical group: n = 27; control group: n = 42). Trait worry levels were collected from all of the participants. Working memory performance was measured as accuracy and reaction time. RESULTS: During the first block, higher worry scores were significantly associated with longer reaction times. Moreover, the generalised anxiety disorder group, clinical group, and subclinical groups demonstrated significantly longer reaction times compared to the control group in Block 1, when age was controlled for. From Block 1 to Block 2, all of the participants demonstrated a significant decrease in accuracy and reaction time, regardless of worry level or clinical status. CONCLUSION: The results indicate that higher worry levels negatively impact WM processing efficiency. Moreover, when age was controlled for, we found participants` clinical status to be linked with WM impairments. The results highlight the relevance of investigating the impact of different worry levels on cognitive processes across clinical and non-clinical populations.

Psychometric Properties of the Aggressive Behaviors Scale from the Youth Self-Report in Juvenile Offenders.

The study of aggression in juvenile offenders, a high priority from clinical and public health standpoints, depends on properly measuring and modeling aggression. The Aggressive Behaviors scale from the Youth Self-Report (YSR-AB) has been widely used to measure youth aggression, often functioning as a stand-alone scale in analyses (of note, even when analyzed alone, the YSR-AB must be administered as part of the full YSR to retain its integrity). However, knowledge of its factor analytic structure among juvenile offenders is lacking. We addressed this gap. Factor analyses of YSR-AB data from 310 probation youth (M age = 16 years, 90% African American, 66% male) supported a hierarchical structure, with 2 lower order factors distinguishing aggression targeting others (e.g., physical attack) from related symptoms (e.g., mood swings). The targeted aggression items showed significantly stronger associations with other externalizing symptoms than did the related symptom items; the opposite pattern emerged for internalizing symptoms. In further support of the convergent and discriminant validity of these subscales, the related symptoms were differentially linked to gender, with females reporting significantly higher levels than males. The hierarchical solution appeared to be stable over 1 year. Implications for interpreting past findings and conducting future research with the YSR-AB are discussed.

Feedback in Couple and Family Therapy: A Randomized Clinical Trial.

Routine Outcome Monitoring (ROM) is recommended as a psychotherapy procedure to serve as clinical feedback in order to improve client treatment outcomes. ROM can work as a warning signal to the therapist if the client shows signs of no change or deterioration. This study has investigated whether any difference in outcome could be detected between those clients in couple and family therapy who used the Systemic Therapy Inventory of Change (STIC) feedback system (ROM condition) versus those who were offered treatment without the use of STIC ("treatment as usual" or TAU condition). A sample of 328 adults seeking couple and family therapy in Norway was randomly assigned to ROM versus TAU conditions. Outcome measures were The Outcome Questionnaire-45 and The Revised Dyadic Adjustment Scale. The results demonstrated no significant differences in outcomes between the ROM and TAU. Possible explanations of this result related to design and implementation issues are discussed.

Cortisol awakening response and additive serotonergic genetic risk interactively predict depression in two samples: The 2019 Donald F. Klein Early Career Investigator Award Paper.

BACKGROUND: The serotonin system and hypothalamic pituitary-adrenal (HPA)-axis are each implicated in the pathway to depression; human and animal research support these systems' cross-talk. Our work implicates a 5-variant additive serotoninergic multilocus genetic profile score (MGPS) and separately the cortisol awakening response (CAR) in the prospective prediction of depression; other work has shown that the serotonin transporter polymorphism 5HTTLPR predicts CAR and interacts with the CAR to predict depression. METHODS: We tested the hypothesis that a 6-variant MGPS (original plus 5HTTLPR) would interact with CAR to predict prospective depressive episode onsets in 201 emerging adults using four annual follow-up interviews. We also tested whether MGPS predicted CAR. We attempted replication of significant findings in a sample of 77 early adolescents predicting depression symptoms. RESULTS: In sample 1, MGPS did not significantly predict CAR. MGPS interacted with CAR to predict depressive episodes; CAR slopes for depression steepened as MGPS increased, for risk or protection. No single variant accounted for results, though CAR's interactions with 5HTTLPR and the original MGPS were both significant. In sample 2, the 6-variant MGPS significantly interacted with CAR to predict depression symptoms. CONCLUSIONS: Higher serotonergic MGPS appears to sensitize individuals to CAR level-for better and worse-in predicting depression.

Trait rumination and response to negative evaluative lab-induced stress: neuroendocrine, affective, and cognitive outcomes.

Theoretical models of depression posit that, under stress, elevated trait rumination predicts more pronounced or prolonged negative affective and neuroendocrine responses, and that trait rumination hampers removing irrelevant negative information from working memory. We examined several gaps regarding these models in the context of lab-induced stress. Non-depressed undergraduates completed a rumination questionnaire and either a negative-evaluative Trier Social Stress Test (n = 55) or a non-evaluative control condition (n = 69), followed by a modified Sternberg affective working memory task assessing the extent to which irrelevant negative information can be emptied from working memory. We measured shame, negative and positive affect, and salivary cortisol four times. Multilevel growth curve models showed rumination and stress interactively predicted cortisol reactivity; however, opposite predictions, greater rumination was associated with blunted cortisol reactivity to stress. Elevated trait rumination interacted with stress to predict augmented shame reactivity. Rumination and stress did not significantly interact to predict working memory performance, but under control conditions, rumination predicted greater difficulty updating working memory. Results support a vulnerability-stress model of trait rumination with heightened shame reactivity and cortisol dysregulation rather than hyper-reactivity in non-depressed emerging adults, but we cannot provide evidence that working memory processes are critical immediately following acute stress.

How to customize a bona fide psychotherapy for generalized anxiety disorder? A two-arms, patient blinded, ABAB crossed-therapist randomized clinical implementation trial design [IMPLEMENT 2.0].

BACKGROUND: Bona fide psychotherapy approaches are effective treatments for generalized anxiety disorder (GAD) compared to no-treatment conditions. Treatment manuals and protocols allow a relatively high degree of freedom for the way therapists implement these overall treatment packages and there is a systematic lack of knowledge on how therapists should customize these treatments. The present study experimentally examines two implementation strategies of customizing a bona fide psychotherapy approach based on a 16 session time-limited cognitive-behavioral therapy (CBT) protocol and their relation to the post-session and ultimate treatment outcomes. METHODS: This trial contrasts two different implementation strategies of how to customize the in-session structure of a manual-based CBT-protocol for GAD. The patients will be randomly assigned to two implementation conditions: (1) a systematic focus on subtle changes lasting from 7 to 20 min at the check-in phase of every psychotherapy session and (2) a state-of-the-art (SOTA) check-in phase lasting several minutes mainly focused on the session goals. Potential therapist effects will be examined based on an ABAB crossed-therapist design. Treatment outcomes will be assessed at the following times: post-session outcomes, treatment outcome at post assessment and 6- as well as 12-month follow-up. DISCUSSION: The proposed randomized clinical implementation trial addresses the clinically relevant question of how to customize a bona fide psychotherapy protocol experimentally contrasting two implementation strategies. Through the development and testing of the proposed implementation design, this trial has the potential to inform therapists about efficacious implementation strategies of how to customize a manual-based treatment protocol in respect to the timing of the in-session structure. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov ( NCT03079336 ) at March 14, 2017.

Testing the convergent and discriminant validity of the Systemic Therapy Inventory of Change Initial scales.

OBJECTIVE: The Systemic Therapy Inventory of Change (STIC®) is the first multi-systemic and multi-dimensional measurement and feedback system designed for assessment in family, couple, and individual functioning. Patients fill out the STIC Initial before the first session to identify treatment targets and provide starting values for subsequent assessments of trajectories of change. This study tested the construct validity of five of the six STIC Initial scales. METHODS: We administered both the STIC Initial and a set of validity measures to a relatively large sample of patients. Convergent and discriminant validity were tested using both an examination of observed correlations and confirmatory factor analysis (CFA). RESULTS: The correlations among the observed measures showed that the convergent validity coefficients were generally large, whereas the discriminant validity coefficients were moderate to small. Similarly, CFAs suggested that the STIC total scales and subscales are good indicators of the factors they were intended to measure and that the STIC total scales and subscales are weakly related to the factors they were intended to not measure. CONCLUSION: The results supported the convergent and discriminant validity of the five scales of the STIC Initial. Clinical or methodological significance of this article: The clinical significance of this article is that it demonstrates that the STIC Initial should be useful for identifying treatment targets including both which systems, in addition to the facets within each system, that require targeting. The methodological significance is twofold. First, the use of CFA for testing convergent and discriminant validity is still relatively rare. Second, we demonstrated how to use CFA for a more stringent test of discriminant validity compared with the original approach described by Cole ( 1987 ).

Anxiety and retrieval inhibition: support for an enhanced inhibition account.

Retrieval inhibition of negative associations is important for exposure therapy for anxiety, but the relationship between memory inhibition and anxiety is not well understood-anxiety could either be associated with enhanced or deficient inhibition. The present study tested these two competing hypotheses by measuring retrieval inhibition of negative stimuli by related neutral stimuli. Non-clinically anxious undergraduates completed measures of trait and state anxiety and completed a retrieval induced forgetting task. Adaptive forgetting varied with state anxiety. Low levels of state anxiety were associated with no evidence for retrieval inhibition for either threatening or non-threatening categories. Participants in the middle tertile of state anxiety scores exhibited retrieval inhibition for non-threatening categories but not for threatening categories. Participants in the highest tertile of state anxiety, however, exhibited retrieval inhibition for both threatening and non-threatening categories with the magnitude of retrieval inhibition being greater for threatening than non-threatening categories. The data are in line with the avoidance aspect of the vigilance-avoidance theory of anxiety and inhibition. Implications for cognitive behavioural therapy practices are discussed.

PATHOLOGICAL PERSONALITY TRAITS AND THE NATURALISTIC COURSE OF INTERNALIZING DISORDERS AMONG HIGH-RISK YOUNG ADULTS.

BACKGROUND: A personality disorder diagnosis signals a negative prognosis for depressive and anxiety disorders, but the precise abnormal personality traits that determine the temporal course of internalizing psychopathology are unknown. In the present study, we examined prospective associations between abnormal personality traits and the onset and recurrence of internalizing disorders. METHODS: A sample of 371 young adults at high risk for internalizing problems completed the Schedule for Nonadaptive and Adaptive Personality-Second Edition--a measure of 12 abnormal personality traits and three temperament dimensions (i.e., Negative Temperament, Positive Temperament, Disinhibition vs. Control)--and underwent annual diagnostic interviews over 4 years of follow-up. RESULTS: In multivariate survival analyses, Negative Temperament was a robust predictor of both new onsets and recurrences of internalizing disorder. Further, the Dependency and Self-Harm abnormal personality dimensions emerged as independent predictors of new onsets and recurrences, respectively, of internalizing disorders after statistically adjusting for variation in temperament. CONCLUSIONS: Our findings suggest that abnormal personality traits and temperament dimensions have complementary effects on the trajectory of internalizing pathology during young adulthood. In assessment and treatment settings, targeting the abnormal personality and temperament dimensions with the greatest prognostic value stands to improve the early detection of enduring internalizing psychopathology.

Confirming, Validating, and Norming the Factor Structure of Systemic Therapy Inventory of Change Initial and Intersession.

UNLABELLED: Progress or feedback research tracks and feeds back client progress data throughout the course of psychotherapy. In the effort to empirically ground psychotherapeutic practice, feedback research is both a complement and alternative to empirically supported manualized treatments. Evidence suggests that tracking and feeding back progress data with individual or nonsystemic feedback systems improves outcomes in individual and couple therapy. The research reported in this article pertains to the STIC(®) (Systemic Therapy Inventory of Change)-the first client-report feedback system designed to empirically assess and track change within client systems from multisystemic and multidimensional perspectives in individual, couple, and family therapy. Clients complete the STIC Initial before the first session and the shorter STIC Intersession before every subsequent session. This study tested and its results supported the hypothesized factor structure of the six scales that comprise both STIC forms in a clinical outpatient sample and in a normal, random representative sample of the U.S. POPULATION: This study also tested the STIC's concurrent validity and found that its 6 scales and 40 of its 41 subscales differentiated the clinical and normal samples. Lastly, the study derived clinical cut-offs for each scale and subscale to determine whether and how much a client's score falls in the normal or clinical range. Beyond supporting the factorial and concurrent validity of both STIC forms, this research supported the reliabilities of the six scales (Omegahierarchical ) as well as the reliabilities of most subscales (alpha and rate-rerate). This article delineates clinical implications and directions for future research.

Examining the long-term stability of overgeneral autobiographical memory.

Overgeneral autobiographical memory (OGM) is a proposed trait-marker for vulnerability to depression, but relatively little work has examined its long-term stability. This study investigated the stability of OGM over several years in 271 late adolescents and young adults participating in a larger longitudinal study of risk for emotional disorders. The Autobiographical Memory Test (AMT) was administered twice, with test-retest intervals ranging from approximately 3 to 6 years. There was evidence of significant but modest stability in OGM over several years. Specifically, Spearman rank correlations (ρs) between the proportions of specific and categoric memories generated on the two AMTs were .31 and .32, respectively. We did not find evidence that the stability of OGM was moderated by the length of the test-retest interval. Furthermore, the stability coefficients for OGM for individuals with and without a lifetime history of major depressive disorder (MDD) were relatively similar in magnitude and not significantly different from one another (ρs=.34 and .42 for the proportions of specific and categoric memories for those with a history of MDD; ρs=.31 for both the proportions of specific and categoric memories for those without a history of MDD). Implications for the conceptualisation of OGM are discussed.

Effects of the serotonin transporter polymorphism and history of major depression on overgeneral autobiographical memory.

Overgeneral autobiographical memory (OGM) is a key memory deficit in major depressive disorder (MDD). Much research has examined cognitive mechanisms underlying OGM, but little work has investigated potential neurobiological influences. There is preliminary evidence that a genetic serotonergic vulnerability coupled with depressive symptoms may be associated with other memory impairments, and experimental research suggests a role for serotonin in OGM. We investigated whether a polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) was associated with OGM in interaction with a lifetime history of MDD in 370 young adults in a longitudinal study of risk for emotional disorders. There was a significant interaction between 5-HTTLPR genotype and lifetime history of MDD in predicting OGM. Among S allele homozygotes, MDD history was associated with greater OGM, whereas no significant relationship between MDD history and OGM emerged among L carriers. Furthermore, there was evidence that a greater number of S alleles were associated with greater memory specificity in individuals without a history of MDD. Implications for understanding cognitive and biological risk for depression are discussed.
