Mental habits: Metacognitive reflection on negative self-thinking

In 8 studies, the authors investigated negative self-thinking as a mental habit. Mental content (negative self-thoughts) was distinguished from mental process (negative self-thinking habit). The negative self-thinking habit was assessed with a metacognitive instrument (Habit Index of Negative Thinking; HINT) measuring whether negative self-thoughts occur often, are unintended, are initiated without awareness, are difficult to control, and are self-descriptive. Controlling for negative cognitive content, the authors found that negative self-thinking habit was distinct from rumination and mindfulness, predicted explicit as well as implicit low self-esteem (name letter effect), attenuated a positivity bias in the processing of self-relevant stimuli, and predicted anxiety and depressive symptoms 9 months later. The results support the assumption that metacognitive reflection on negative self-thinking as mental habit may play an important role in self-evaluative processes.

A New Scale for Adolescent Resilience: Grasping the Central Protective Resources Behind Healthy Development

Abstract In this study, the Resilience Scale for Adolescents (READJ was developed with confirmatory factor analysis and cross-validated factor model. The results show that the READ has sound psychometric qualities and that it measures all the central aspects of the psychological construct of resiliency.

Validating the Eating Disorder Inventory-3 (EDI-3): A Comparison Between 561 Female Eating Disorders Patients and 878 Females from the General Population

The Eating Disorder Inventory (EDI) is used worldwide in research and clinical work. The 3rd version (EDI-3) has been used in recent research, yet without any independent testing of its psychometric properties. The aim of the present study was twofold: 1) to establish national norms and to compare them with the US and international norms, and 2) to examine the factor structure, the internal consistency, the sensitivity and the specificity of subscale scores. Participants were Danish adult female patients (N = 561) from a specialist treatment centre and a control group (N = 878) was women selected from the Danish Civil Registration system. Small but significant differences were found between Danish and international, as well as US norms. Overall, the factor structure was confirmed, the internal consistency of the subscales was satisfactory, the discriminative validity was good, and sensitivity and specificity were excellent. The implications from these results are discussed.

Resilience as a Predictor of Depressive Symptoms: A Correlational Study with Young Adolescents:

This correlational study explored the Resilience Scale for Adolescents (READ)1 as a predictor for developing depressive symptoms controlling for known risk factors. A young adolescent sample (N = 387) completed the READ, the Short Mood and Feeling Questionnaire (SMFQ), Social Phobia Anxiety Index for Children (SPAI-C), and the occurrence of Stressful Life Events (SLE). In addition, a subsample of their parents (N = 240) completed a parental version of READ (READ-P). The results indicated that the READ assesses important protective factors that are associated with fewer depressive symptoms among young adolescents even when controlling for known risk factors. All five READ-factors were predictors of depressive symptoms, while the READ-P showed no predictive value. There were no significant interaction effects between READ and SLE. There were, however, significant main-effects supporting a compensatory model of protective factors. The findings suggest that the READ is a significant predictor of mental health and a useful tool for further research examining differences in stress tolerance among young adolescents.

Comorbidity of personality disorders in anxiety disorders: A meta-analysis of 30 years of research

BACKGROUND A comprehensive meta-analysis to identify the proportions of comorbid personality disorders (PD) across the major subtypes of anxiety disorders (AD) has not previously been published. METHODS A literature search identified 125 empirical papers from the period 1980-2010 on patients with panic disorders, social phobia, generalised anxiety, obsessive-compulsive (OCD) and post-traumatic stress disorder (PTSD). Several moderators were coded. RESULTS The rate of any comorbid PD was high across all ADs, ranging from .35 for PTSD to .52 for OCD. Cluster C PDs occurred more than twice as often as cluster A or B PDs. Within cluster C the avoidant PD occurred most frequently, followed by the obsessive-compulsive and the dependent PD. PTSD showed the most heterogeneous clinical picture and social phobia was highly comorbid with avoidant PD. A range of moderators were examined, but most were non-significant or of small effects, except an early age of onset, which in social phobia increased the risk of an avoidant PD considerably. Gender or duration of an AD was not related to variation in PD comorbidity. LIMITATIONS Blind rating of diagnoses was recorded from the papers as an indication of diagnostic validity. However, as too few studies reported it the validity of the comorbid estimates of PD was less strong. CONCLUSIONS The findings provided support to several of the proposed changes in the forthcoming DSM-5. Further comorbidity studies are needed in view of the substantial changes in how PDs will be diagnosed in the DSM-5.

Comorbidity of personality disorders in mood disorders: A meta-analytic review of 122 studies from 1988 to 2010

BACKGROUND A meta-analysis was conducted to identify the proportions of comorbid personality disorders (PD) in mood disorders. METHODS We found 122 empirical papers published in the period 1980-2010 on participants having mood disorders in addition to a comorbid PD. Mood disorders were classified as bipolar disorders (BD), major depressive disorders (MDD) and dysthymic disorders (DYS). Several moderators were coded as well. RESULTS The risk of having at least one comorbid PD (any PD) was high across all three mood disorders (BD=.42, MDD=.45), but highest in DYS (.60). Cluster B and C PDs were most frequent in BD, while cluster C PDs dominated in MDD and DYS. Among the specific PDs, the paranoid (.11 versus .07/.05), borderline (.16 versus .14/.13), histrionic (.10 versus .06/.06) and obsessive-compulsive (.18 versus .09/.12) PDs occurred more frequently in BD versus MDD/DYS, whereas the avoidant PD (.22 versus .12/.16) was most frequent in DYS versus BD/MDD. Moderator analyses showed higher comorbidity when diagnoses were based on questionnaires versus clinical interviews, DSM-III-R versus DSM-IV, more women were included or the duration of the disorder was longer. Age of onset yielded mixed results. LIMITATIONS Blind rating of diagnoses was recorded, but was employed in too few studies to be usable as an indication of diagnostic validity. CONCLUSIONS Personality disorders are common in mood disorders. Implications of the identified moderators as well as the new DSM-5 diagnostic system are considered.

Empirical Support for Resilience as More than the Counterpart and Absence of Vulnerability and Symptoms of Mental Disorder

The construct of resilience has been viewed as the direct counterpart of factors jeopardizing mental health, i.e., vulnerability and psychopathology. Any operationalization of resilience, thus, risks lying on the same latent continuum as indicators of mental illness, although indicating their absence. A factor analysis combining items from these measurement domains, followed by analyses of second-order factor scores was performed to test this assumption. A random selection of 1,724 participants (34% response rate) from the general population of Norway responded. All items were discriminated well by their primary factors. A second-order factor analysis extracted two components, which was confirmed on a hold-out sample by confirmatory factor methods. The Resilience Scale for Adults (RSA), which measures protective factors, correlated with both second-order factors. Thus, the RSA shared common variance with vulnerability and psychopathology, as well as being unique from illness indices. A hierarchical regres...

Associations between seasonal variations in day length (photoperiod), sleep timing, sleep quality and mood: a comparison between Ghana (5°) and Norway (69°).

The hypothesis of whether day length (photoperiod) is an important zeitgeber (time‐giver) for keeping the circadian rhythm entrained to a 24‐hour cycle was examined, as was its association with sleep patterns and mood problems. Data were collected prospectively from a site with very large differences in daylight duration across seasons (Tromsø in Norway, 69°39′N) and a site with very small seasonal differences in daylight duration (Ghana in Accra, 5°32′N). Two hundred subjects were recruited from both sites in January. At the follow‐up in August, 180 and 150 subjects in Ghana and Norway participated, respectively. Use of a weekly sleep diary indicated low to moderately strong seasonal changes in rise‐ and bedtime, sleep efficiency and sleep onset latency only in the northern latitude. No seasonal changes in sleep duration or night awakenings were observed. The self‐report measures indicated moderate to strong seasonal differences in insomnia and fatigue, and weaker differences in depressed mood in Norway, but small to non‐existing seasonal differences in Ghana. Lack of daylight was related to phase‐delayed rise‐ and bedtimes, increased problems falling asleep, daytime fatigue and depressive mood. However, total sleep duration and sleep quality appeared unaffected.

Cross‐cultural validation of the Resilience Scale for Adults (RSA) in Iran

Resilience, as an ability to withstand and rebound from crisis and adversity, is becoming an increasingly popular concept in research on intervention and prevention of mental health. The present study examined psychometric properties of a Persian version of the Resilience Scale for Adults (RSA), a scale intended to measure protective factors presumed to enhance resilience. The participants were 373 university undergraduate students, as well as 30 pairs of run-away girls and a matched control group. A confirmatory factor analysis verified the Norwegian five-factor structure. All subscale scores, personal competence, social competence, family cohesion, social resources and structured style, had good reliability. The convergent validity of the RSA was supported by showing positive associations with another resilience scale, i.e., a Persian version of the Connor-Davidson Resilience Scale (CD-RISC). Predictive validity of the RSA was supported, as well, by significantly differentiating between girls who had run away from home and a matched control group. The results indicate that the RSA may be a valid and reliable scale for the assessment of resilience protective resources in an Iranian population.

The Resilience Scale for Adults: Construct Validity and Measurement in a Belgian Sample

The Resilience Scale for Adults (RSA) was developed and has been extensively validated in Norwegian samples. The purpose of this study was to explore the construct validity of the Resilience Scale for Adults in a French-speaking Belgian sample and test measurement invariance between the Belgian and a Norwegian sample. A Belgian student sample (N = 363) completed the RSA, the Hopkins Symptom Checklist-25 (HSCL-25), and Sense of Coherence Scale (SOC-29). A Norwegian second sample (N = 315) was included in the analyses of invariance of the RSA. There were expected positive and negative significant correlations with SOC-29 and HSCL-25, respectively. The metric invariance was supported, with the exception of one of the six RSA factors. The findings demonstrate that the RSA may be a valid and reliable self-report measure of protective factors and further the results also indicated cross-cultural validity for the RSA in a French-speaking Belgian sample.
