Challenges in the early detection of patients with psychotic spectrum disorder or bipolar disorder in rural Grete/Greece: The role of the mobile mental health unit
Background: Early detection and intervention are considered important determinants of long-term outcomes of severe mental disorders. Preliminary evidence has shown that in Crete/Greece in rural areas there is a significant delay in seeking mental health care for patients with psychosis or bipolar disorder. Aims/objectives: The primary aim of this study is to examine: the mean age and percentage of involuntary admissions of patients with psychotic…
Early maladaptive schema domains and suicide risk in major depressive disorder: The mediating role of patients’ illness-related self-regulation processes and symptom severity
Early maladaptive schemas (EMS), illness representations, and coping are associated with clinical outcomes of patients with major depressive disorder (MDD). However, the pathways that link these factors are largely unknown. The present prospective study aimed at investigating the possible mediating role of illness representations and coping in the associations among schema domains, symptom severity, and suicide risk in MDD. Participants were 135 …

The relation of partners’ illness representations to the coping behaviors of patients with inflammatory rheumatic diseases through patients’ illness representation: A dyadic regulation process
Suicidality Prevalence in a Pediatric Psychiatric Clinic: Relation to Social and Environmental Risk Factors
Suicidality is a growing public health problem in children and adolescents. The aim of this retrospective data analysis study was to estimate the prevalence of suicidality in pediatric patients admitted to an academic Pediatric Psychiatric Clinic (PPC) and to analyze social and environmental risk factors associated with suicide. Suicidal ideation was assessed by the Self-Injurious Thoughts and Behaviors Interview. Using established psychometric s…
Behavioral, neurocognitive, polysomnographic and cardiometabolic profiles associated with obstructive sleep apnea in adolescents with ADHD
BACKGROUND: A high comorbidity between attention-deficit/hyperactivity disorder (ADHD) and obstructive sleep apnea (OSA) as well as similar impairments across neurobehavioral outcomes has been described in children. However, there is a paucity of research examining the comorbidity of these two disorders in adolescents. This study examined the association of OSA with sleep, neurobehavioral, and cardiometabolic outcomes in adolescents with ADHD fro…
The impact of mild cognitive impairment on the self-regulation process: A comparison study of persons with mild cognitive impairment and cognitively healthy older adults
This study examined whether mild cognitive impairment affects the associations between personal expectations (i.e. optimism and self-efficacy), illness-related coping, and quality of life. In total, two groups of older adults participated: 127 persons diagnosed with mild cognitive impairment and 225 cognitively healthy older persons (cognitively non-impaired group). Several significant relationships observed in the cognitively non-impaired group …
Identifying the socio-demographic and clinical determinants of family functioning in Greek patients with psychosis
BACKGROUND: Studies on determinants affecting family functioning of patients with psychosis are still limited in Greece. AIM: The aim of this study was to describe the socio-demographic and clinical characteristics associated with family functioning in patients with schizophrenia and bipolar disorder in Crete, Greece. METHODS: A total of 100 patients and their caregivers agreed to participate in the study. Family functioning was assessed in terms…
Family Functioning in First-Episode and Chronic Psychosis: The Role of Patient’s Symptom Severity and Psychosocial Functioning
Cross-Cultural Adaptation and Validation of the Greek Version of the Family Adaptability and Cohesion Evaluation Scales IV Package (Faces IV Package)
The aim of the present study was to examine the psychometric properties of the Greek version of Family Adaptability and Cohesion Evaluation Scales IV (FACES IV) Package. The original FACES IV displays a six-factor structure with two balanced scales-Balanced Cohesion and Balanced Flexibility-and four unbalanced scales-Disengaged, Enmeshed, Rigid, and Chaotic-and has been shown to have satisfactory internal and test-retest reliability. A total of 5…
Sleep Misperception and Chronic Insomnia in the General Population: Role of Objective Sleep Duration and Psychological Profiles
OBJECTIVE: To examine the role of objective sleep duration, a novel marker in phenotyping insomnia, and psychological profiles on sleep misperception in a large, general population sample. Sleep misperception is considered by some investigators a common characteristic of chronic insomnia, whereas others propose it as a separate diagnosis. The frequency and the determinants of sleep misperception in general population samples are unknown. METHODS:…
Cognitive-Emotional Hyperarousal as a Premorbid Characteristic of Individuals Vulnerable to Insomnia
OBJECTIVE: To examine whether cognitive-emotional hyperarousal is a premorbid characteristic of middle-aged and young good sleepers vulnerable to stress-related insomnia. METHODS: Self-reported information was collected from two samples of 305 middle-aged and 196 young adults. From those adults, 149 middle-aged (50.34 +/- 4.47 years) and 85 young (20.19 +/- 1.31 years) good sleepers were selected for the present study. The Ford Insomnia Response …
Differences in Nocturnal and Daytime Sleep Between Primary and Psychiatric Hypersomnia: Diagnostic and Treatment Implications
OBJECTIVE: The differential diagnosis of primary (idiopathic) vs. psychiatric hypersomnia is challenging because of the lack of specific clinical or laboratory criteria differentiating these two disorders and the frequent comorbidity of mental disorders in patients with primary hypersomnia. The aim of this study was to assess whether polysomnography aids in the differential diagnosis of these two disorders. METHODS: After excluding patients takin…
