The Adaptation, Validity and Reliability Study of Turkish Metacognitive Beliefs about Health Anxiety Questionnaire (MCQ-HA).

Objective: The aim of the present study was to adapt the Metacognitive Beliefs about Health Anxiety Questionnaire (MCQ-HA) to Turkish, and to evaluate its psychometric properties.

Method: The study consisted of 631 participants, 146 of whom were diagnosed with a physical illness, while 485 of whom did not have any physical illness.

Results: As similar to its original form, factor analysis results confirmed a three-factor structure in samples with and without physical illness, as well as in the total sample.

Investigation of the Metacognitive Model of Depression in a Turkish Sample of Major Depressive.

Objective: The aim of this study was to test the metacognitive model of depression in individuals diagnosed with major depressive disorder (MDD) and to investigate the relative contributions of cognitions and metacognitions about rumination to the explanation of depressive symptoms.

Method: The participants of the study consisted of 180 MDD patients not meeting the diagnostic criteria for other psychiatric disorders. The obtained data were analyzed through structural equation modelling (SEM) and hierarchical regression analyses.

The Role of Metacognitions on the Relationship Between Adult Attachment and Mood Symptoms in Individuals with Obesity.

In order to examine psychological mechanisms contributing to the development and maintenance of mood symptoms experienced by individuals with obesity, this study focused on the mediator role of metacognitions in the relationship between adult attachment dimensions (anxious and avoidant) and mood symptoms (depression and anxiety). A 184 individuals with Body Mass Index (BMI) of 30 or above completed a battery of instruments including measures of attachment styles, metacognitive beliefs and processes, depression, and anxiety symptoms. Multiple mediation analyses with bootstrapping demonstrated that while attachment anxiety was predictive of greater levels of depression and anxiety through the effect of beliefs about uncontrollability and dangerousness of worry, metacognitive factors have no mediator role in the relationship between avoidant attachment and mood symptoms.

[Examination of the Metacognitive Model of Depression in a Turkish University Student Sample].

Aim: The aim of the present study is to test the metacognitive model of depression in a Turkish sample using structural equation modeling.

Method: A total of 305 university students participated in this study. The data concerning the levels of rumination, positive beliefs about rumination (positive beliefs), negative beliefs about uncontrollability and harm of rumination (negative beliefs-1), negative beliefs about interpersonal and social consequences of rumination (negative beliefs-2), lack of cognitive confidence, and depression was collected using a web-survey method.

[Psychometric Properties of the Metacognition Scales about Rumination in Clinical and Non-clinical Turkish Samples].

Aim: The aim of this study is to examine the reliability and validity of the Turkish adaptations of the Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) in clinical and non-clinical samples.

Method: While the non-clinical sample of the study consisted of 455 participants, the clinical sample was composed of 60 major depressive disorder (MDD), 30 panic disorder (PD) and 30 social anxiety disorder (SAD) cases.

Results: The results of the factor analyses confirm the construct validity and original factor structure of the scales.

[The Role of Worry and Rumination in the Symptoms of Anxiety and Depression].

Aim: The aim of this study is to examine the unique and interactive role of worry and rumination in anxiety and depression symptoms.

Method: A total of 328 university students responded to questionnaires assessing worry (Penn State Worry Questionnaire), rumination (Ruminative Response Styles Questionnaire-Short Form), anxiety (Beck Anxiety Inventory and Trait Anxiety Inventory), and depression (Beck Depression Inventory).

Results: The results of regression analyses demonstrated that the relationship between worry and depressive symptoms is significant only if individuals engage in high levels of brooding type rumination.

Unique contributions of metacognition and cognition to depressive symptoms.

This study attempts to examine the unique contributions of "cognitions" or "metacognitions" to depressive symptoms while controlling for their intercorrelations and comorbid anxiety. Two-hundred-and-fifty-one university students participated in the study. Two complementary hierarchical multiple regression analyses were performed, in which symptoms of depression were regressed on the dysfunctional attitudes (DAS-24 subscales) and metacognition scales (Negative Beliefs about Rumination Scale [NBRS] and Positive Beliefs about Rumination Scale [PBRS]).

The mediator role of ruminative thinking style in the relationship between dysfunctional attitudes and depression.

Background: The main aim of the present study was to examine whether ruminative thinking styles (brooding and reflection) mediate the effects of dysfunctional attitudes on depressive symptoms.

Methods: 120 psychotropic drug-naive first episode depression patients recruited from Bulent Ecevit University School of Medicine psychiatry department and Zonguldak State Hospital psychiatry department outpatient clinics were involved in the study. Participants completed the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Beck Depression Inventory (BDI), Dysfunctional Attitude Scale (DAS) and Ruminative Responses Scale (RRS-short version).
