Relationships between Recent Suicidal Ideation and Recent, State, Trait and Musical Anhedonias in Depression
The aim of the study was to explore in depression the relationship between recent suicidal ideation and the different anhedonias taking into account the severity of depression. Recent studies have suggested that recent change of anhedonia and not state or trait anhedonia is associated with recent suicidal ideations even when the level of depression is controlled. Three samples were used (74 severe major depressives, 43 outpatients with somatic di…
Prevalence and Relationships between Alexithymia, Anhedonia, Depression and Anxiety during the Belgian Covid-19 Pandemic Lockdown
Alexithymia and anhedonia are associated with psychiatric disorders, such as depression and anxiety. The COVID-19 pandemic lead to a significant deterioration in the mental health of the population. It is therefore important to examine the effects of lockdown on alexithymia and anhedonia and their relationships with anxiety and depression. We compared the scores and characteristics of 286 patients divided into two groups: one before lockdown (gro…
The Interpersonal–Psychological Theory of Suicide in Medical Students
The aim of this study was to explore the interpersonal-psychological theory of suicide (IPTS) in medical students. Higher levels of thwarted belongingness and perceived burdensomeness were expected in medical students with suicidality compared with medical students without suicidality, and a high level of acquired capability was expected in planners compared with ideators. Recruited for the study were 178 undergraduate medical students at the Uni…

The aim of the study was to explore the relationships between recent changes of anhedonia or particular symptoms of recent changes of anhedonia and suicidal ideation taking into account the severity of suicidal ideations. In a group of 173 medical students, scores of the anhedonia subscale (ANH-BDI) of the BDI-II (i.e. 4 anhedonia items: loss of pleasure, loss of interest, loss of energy and loss of interest in sex) were compared between 95 subje…
Psychometric properties of the Arabic version of the Alexithymia Questionnaire for Children (AQC) in children and adolescents
This study had the aim to explore the psychometric properties of the Arabic version of the Alexithymia Questionnaire for Children (AQC) that measures the three dimensions of alexithymia (DIF, difficulty identifying feelings; DDF, difficulty describing feelings; EOT, externally oriented thinking). 817 healthy children or adolescents (407 girls, 410 boys) with a mean age of 12.10 years (SD = 1.91, range from 9 to 16 years) were included in the stud…
Type D personality
The aim of this study was to validate the French-language version of the Type D personality scale-14 among general and clinical populations (acute coronary syndrome and breast cancer patients). The two-factor structure of the Type D personality scale-14 was confirmed by factorial and confirmatory analyses. Internal consistency for both subdimensions of Type D personality scale-14 (negative affectivity and social inhibition) was very good with α =…
Determination of the Cutoff Threshold on the Bermond-Vorst Alexithymia Questionnaire–20 Form B
The aim of the study was to calculate the cutoff scores on the Bermond-Vorst Alexithymia Questionnaire-20 Form B. 560 students completed the Bermond-Vorst Alexithymia Questionnaire-20 Form B and the 20-item Toronto Alexithymia Scale. Using cutoff scores of the French or the original version of the 20-item Toronto Alexithymia Scale as the standard, the participants were divided into alexithymic and non-alexithymic groups. The Bermond-Vorst Alexith…
Relationship between Type D Personality and Anhedonia
Type D personality-characterized by negative affectivity and social inhibition-and anhedonia have independently been found to be significantly associated with depression or suicidal ideation in the general population or in psychiatric subjects. The aim of the study was to evaluate the association between Type D personality and anhedonia in a population of 204 university students (102 men, 102 women) after controlling for depression as a confoundi…
Self-Report of Empathy
For more than 30 years, the Interpersonal Reactivity Index (IRI) has been used to measure the multidimensional aspects of empathy. But the 28-item, 4-factor model of Davis (1980 ) is currently contested because of methodological issues and for theoretical reasons. Confirmatory (CFA) and exploratory factor analyses (EFA) were applied in two French-speaking Belgian student samples (1,244 participants in the first and 729 in the second study) to tes…
Criterion Validity of the Cognitive Slippage and Schizotypal Ambivalence Scales
This study explored the criterion-validity of the Cognitive Slippage Scale (CSS) and the Schizotypal Ambivalence Scale (SAS). 27 first-degree relatives of individuals with schizophrenia (9 males, 18 females; M age=45.3 yr., SD=13) were compared with 30 first-degree relatives of non-psychotic patients (15 males, 15 females; M age = 44.6 yr., SD = 11.6) on the French versions of the CSS and SAS. The former group, who is at high risk for schizophren…
Anhedonia in Kraepelinian Schizophrenia
Kraepelinian schizophrenia, defined as a severe form of the disease, is characterized by a high number of negative symptoms and less depression, respectively. The relationship between anhedonia and Kraepelinian schizophrenia was explored. Depressive and trait anticipatory and consummatory anhedonia were compared in Kraepelinian (n=10, M age 49.2 yr., SD=10.8) and non-Kraepelinian (n=23, M age=42.7 yr., SD=10.8) patients with schizophrenia. The Kr…
Subjective Experiences in First-Degree Relatives of Schizophrenic Subjects
First-degree relatives of patients with schizophrenia may score higher on the Frankfurt Complaint Questionnaire (FCQ) than controls. The present study was designed to provide evidence of validity for the French version of the 24-item subscale of the Frankfurt Complaint Questionnaire (FCQ-24). In 27 first-degree relatives of patients with schizophrenia (high-risk group) and 30 controls, the high-risk group scored significantly higher on the FCQ, a…
Test-Retest Reliability of the Frankfurt Complaint Questionnaire
Long-term reliability of the Frankfurt Complaint Questionnaire (FCQ) was investigated in two follow-up studies of participants with psychosis using a test-retest method. In the first study (N = 56), the duration of the follow-up ranged from 6 months to 2 years; Spearman rho was .62 for the abridged (18 items) Spanish version of the questionnaire. In Study 2 (N = 21), in participants with stable schizophrenia, the follow-up ranged from 8 to 11 yea…
Alexithymia in Severely Obese Patients Seeking Surgical Treatment
The purpose of the study was to examine the rate of alexithymia as measured by the Toronto Alexithymia Scale in a sample of severely obese subjects, as well as the relationships between this dimension and five other dimensions found in obesity: depression, anhedonia, external locus of control, impulsivity, and interpersonal dependency. A second purpose was to test the hypothesis that alexithymia could be a prognosis factor in severely obese subje…
Risk Factors for Addictive Disorders
Many common risk factors have been described in addictive disorders. Little is known about factors' respective contributions to discrimination of addicted and nonaddicted participants. Two large samples were compared including 513 nonpsychiatric participants and 374 addicted participants meeting the DSM-IV criteria for eating disorders, alcohol, or substance dependence. Twenty-six risk factors were assessed by interview or self-rating scales. A d…
Anhedonia and Suicide
This was a prospective follow-up study of suicidal patients to assess the association of anhedonia, depression, and completed suicides. Survival analysis as well as Cox's regression makes it possible to weigh the influence of variables. A cohort of 106 patients (81 women, 25 men, M age=33 yr., SD=9.9) admitted to medical or surgical departments after a suicide attempt was followed during a 6.5-yr. mean observation period. In total, 6.7% of patien…
Criterion Validity of Bermond-Vorst Alexithymia Questionnaire-20 Form B
The aim of the study was to set alexithymia cutoff scores on the 20-item Bermond-Vorst Alexithymia Questionnaire-20 Form B. Alexithymia is a clinical construct describing individuals who have difficulty identifying and reporting their specific emotions. 63 subjects meeting the DSM-IV criteria for alcohol dependence completed the questionnaire and the 20-item Toronto Alexithymia Scale. Using cutoff scores for the latter, subjects were divided into…
Relationships between Hallucinations and Disorganization in Schizophrenic Patients
In two samples of 150 and 310 schizophrenic patients, scores for hallucinations were significantly associated with scores on disorganization
Psychoaffective Immaturity in Psychiatric Disorders
This study investigated the prevalence of psychoaffective immaturity and tested the hypothesis that it associated with bad prognosis. For 135 psychiatric patients meeting criteria for personality, neurotic, affective, substance use, or psychotic disorders emotional immaturity was rated using the 1985 diagnostic criteria of Doutheau, Dubertret, Moutin, and Barrois. 58 subjects (42.96%, 95% Confidence Interval: 34.61-51.31) were classified as immat…
