Depressive symptoms and loneliness among early adolescents: a psychometric network analysis approach.

BACKGROUND: Previous studies demonstrate a high prevalence of depression and loneliness among adolescents. Although they often co-occur, the relationship between symptoms of depression and loneliness remains poorly understood. This study investigates: (a) the symptoms of depression that are connected to loneliness; (b) the role played by loneliness in the network of depression symptoms; and (c) whether the method used to measure loneliness (single-item direct or multi-item indirect) affects the relationship of loneliness with depressive symptoms. METHODS: Participants were 496 Polish adolescents (50.8% girls) aged 11 to 13, who completed: (a) the 10-item Major Depressive Disorder subscale of the Revised Child Anxiety and Depression Scale; (b) the 11-item De Jong Gierveld Loneliness Scale (indirect loneliness), and (c) a single direct question evaluating loneliness: 'I'm lonely'. Networks were estimated using a Gaussian Graphical Model. RESULTS: Loneliness shows a direct relationship with three affective symptoms of depression: sadness, worthlessness, and anhedonia, which mediate relationships with somatic symptoms. In contrast to previous studies, loneliness has the lowest level of centrality among all elements of the network. The method used to assess loneliness did not significantly affect the connections between loneliness and depressive symptoms. CONCLUSIONS: Loneliness and depression overlap since they are formed by the same cognitive biases and deficits in emotion regulation but differ in the level of generality. In loneliness, they have an interpersonal context, while symptoms of depression can be intrapersonal. This helps us to understand why cognitive interventions, as compared to those which are social, are more effective in reducing loneliness.

The Stigma subscale of the Consumer Experiences of Stigma Questionnaire (CESQ): a psychometric evaluation in Polish psychiatric patients.

OBJECTIVE: There is a scarcity of well validated measures of the subjective experience of the stigma of mental illness. The aim of this paper was to evaluate the psychometric properties of the Stigma subscale of the Consumer Experiences of Stigma Questionnaire (CESQ). METHODS: A secondary analysis of the data from two cross-sectional studies using the CESQ was conducted in order to assess the factor structure, internal consistency and concurrent validity of the Stigma subscale. Sample 1 included 373 diagnostically heterogeneous patients (65% had psychotic disorders) and Sample 2 included 136 patients with schizophrenia. RESULTS: Since none of the factor models of the original 9-item scale was satisfactory, it was shortened by removing two psychometrically weakest items. The abbreviated 7-item scale proved to be a one-dimensional instrument, with good estimates of internal consistency. Its concurrent validity was partly confirmed by demonstrating negative correlation with quality of life and positive correlations with self-rated psychopathological symptoms. However, contrary to theoretical expectations, the stigma score was not associated with global functioning and clinician-rated symptoms. CONCLUSIONS: The psychometric properties of the Stigma subscale of the CESQ may be improved by shortening the instrument. Although the reliability and validity of the abbreviated version were partly established, further research is needed to explore in particular its test-retest reliability and concurrent validity.

Using the De Jong Gierveld Loneliness Scale With Early Adolescents: Factor Structure, Reliability, Stability, and External Validity.

The present investigation is the first examination of the factor structures, reliability, external validity, longitudinal invariance, and stability of the De Jong Gierveld Loneliness Scale (DJGLS), as used with early adolescents. It is based on a two-wave, large, representative sample of Polish primary school pupils. The results demonstrate that the model most reflective of the factor structure of the DJGLS is the bifactor model, which assumes the occurrence of one, highly reliable, general factor (overall sense of loneliness) and two, relatively irrelevant, subfactors. Essential unidimensionality (the general factor accounting for three fourth of the common variance) suggest that the interpretation of the subfactors over and above the general factor is inappropriate. The longitudinal confirmatory factor analysis indicated that the bifactor structure of the DJGLS is invariant over time. Correlations with self-rated loneliness, sociometric acceptance/rejection, social self-efficacy, identification with class group, family structure, and gender provide support for the validity of the DJGLS. This implies that it could be used as a measure of loneliness in adolescence, which does not involve references to the school context, making it possible to conduct studies that go beyond school period and compare the intensity of the feeling of loneliness in that group with other age groups.

Peer Rejection and Perceived Quality of Relations With Schoolmates Among Children With ADHD.

OBJECTIVE: The main aim of the current study was to investigate the links between ADHD diagnosis and the objective and subjective dimensions of social relationships among children from primary schools. METHOD: We used the data from 36 regular classrooms, consisting of 718 students, with each containing at least one child with an established clinical diagnosis of ADHD (38 children). RESULTS: For children with ADHD, the level of the perceived quality of social relations was lower than that of children without such a diagnosis. After controlling for sociometric status, the impact of ADHD on perceived status proved to be statistically nonsignificant but the indirect impact of ADHD on this status through sociometric status was statistically significant. CONCLUSION: Children diagnosed with ADHD are more often rejected by their peers and have a more pessimistic view of their social world. Moreover, ADHD diagnosis does not have a direct influence on the perceived quality of social relations otherwise than through sociometric status.
