Many of the scales demonstrated weak psychometrics in at least one of the following ways: (a) lack of psychometric data [i.e., reliability and / or validity; e.g., HFQ, MASC, PBS, Social Adjustment Scale - Self - Report (SAS - SR) and all perceived self - esteem and self - concept scales], (b) items that fall on more than one subscale (e.g., CBCL - 1991 version), (c) low alpha coefficients (e.g., below.60) for some subscales, which calls into question the utility of using these subscales in research and clinical work (e.g., HFQ, MMPI - A, CBCL - 1991 version, BASC, PSPCSAYC), (d) high correlations
between subscales (e.g., PANAS - C), (e) lack of clarity regarding clinically - relevant cut - off scores, yielding high false positive and false negative rates (e.g., CES - D, CDI) and an inability to distinguish
between minor (i.e., subclinical) and major (i.e., clinical) «cases» of a disorder (e.g., depression; CDI, BDI), (f) lack of correspondence
between items and DSM criteria (e.g., CBCL - 1991 version, CDI, BDI, CES - D, (g) a
factor structure that lacks clarity across studies (e.g., PSPCSAYC, CASI; although the
factor structure is often difficult to assess in studies of pediatric populations, given the small sample sizes), (h) low inter-rater reliability for interview and observational methods (e.g., CGAS), (i) low correlations
between respondents such as child, parent, teacher [e.g., BASC, PSPCSAYC, CSI, FSSC - R, SCARED, Connors Ratings Scales - Revised (CRS - R)-RSB-, (j) the inclusion of somatic or physical symptom items on mental health subscales (e.g., CBCL), which is a problem when conducting studies of children with pediatric physical conditions because physical symptoms may be a feature of the condition rather than an indicator of a mental health problem, (k) high correlations with measures of social desirability, which is particularly problematic for the self - related rating scales and for child - report scales more generally, and (l) content validity problems (e.g., the RCMAS is a measure of anxiety, but contains items that tap mood, attention, peer interactions, and impulsivity).

factors structure of the scale was tested by means of a confirmatory
factor analysis, (b) various types of reliability were investigated including the internal consistency, test — retest reliability, and cross-informant agreement, and (c) several aspects of the validity were explored such as the relations with anxiety and internalizing (i.e., convergent validity) and externalizing (i.e., divergent validity) symptoms as well as the relations

Meantime, we hypothesize a dynamic relationship

factors based on the assumption that the affective experiences that children collect via their emotion regulation efforts will influence the cognitive

factors which make managing A1C particularly difficult for teens including: Social pressures and responsibilities, motivation, personality, nutrition, substance use, sleep habits, brain re-structuring, defence mechanisms (such as denial and avoidance), social justice issues (oppresion — racism), diabetes education, individuation, future - oriented culture, access to health services, family
structure and dynamic issues, marital conflict
between parents, family and friendship conflict with teen, mental health stigma, academic pressure and responsibility, limited mindfulness and somatic awareness, spirituality (especially concerning death), an under - developed ability to conceptualize long - term cause and effect (this is developmentally normal for teens), co-parenting discrepencies, emotional inteligence, individuation, hormonal changes, the tendency for co-morbidity (people with diabetes can be more prone to additional physical and mental health diagnosis), and many other life / environmental stressors (poverty, grief etc.).

Against this background, the aims of the current study were to (a) confirm the six -
factor structure of the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, Journal of Psychopathology and Behavioral Assessment, 23 (4), 253 — 263, 2004) in a sample of adolescent inpatients (N = 218); (b) explore the relation
between different aspects of emotion dysregulation and lifetime NSSI while controlling for psychopathology and sex; and (c) assess the clinical utility of the DERS in detecting lifetime NSSI status.
We also fit models that included interaction terms (e.g., family functioning * family
