Prior research from both ASPN and PROS confirms the comparability of patients, clinicians, and practices participating in primary care networks studies with those identified in national samples.34 - 37 A survey conducted as part of the Child Behavior Study38 showed no difference in demographic factors, practice characteristics, or attitudes toward psychosocial problems among participating pediatricians and a random sample of primary care pediatricians from the American Academy of Pediatrics.
Previous research from the former waves of the Bergen Child Study (a longitudinal study nested within youth@hordaland) has also identified psychological problems as a predictor for non - participation.70 As the current sample may be skewed towards better socioeconomic status and psychological health, the results may be a conservative estimate of the number of adolescents growing up in poor families and their associated mental health problems.
Learners focus on becoming educated consumers of research and examine major concepts and techniques of social science research, including problem formulation, identification of variables, literature review, research design, sampling, definition and measurement of study variables, instrument construction, and data collection and analysis.
A substantial body of research indicates that regardless of race and age, female offenders have higher rates of mental health problems, both internalizing and externalizing, than male offenders.19 In a study of serious «deep - end» offenders, females exhibited both more externalizing problems and more internalizing problems than males.20 Moreover, a recent study using common measures and a demographically matched sample of community and detained youth found that gender differences were greater among detained youth than among community youth, with detained girls having more symptoms of mental illness than would be predicted on the basis of gender or setting alone.21
Introductory course in research methodology for the social sciences: formulation of a research problem, design, sampling, data collection, measurement, data analysis, interpretation, and writing the research report.
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).
Several of the most commonly identified risk factors in previous research were identified in this study, including being male, membership in a single - parent or stepfamily, 5 high levels of parent - reported childhood activity, 23,24 maternal mental health problems, 25 and a history of teenage parenthood.26 What is relatively novel about this report is the consideration of the joint effects of psychosocial risk factors, while controlling for multiple indicators of social class and the assessment of both accidents and illnesses in a large community sample followed prospectively since pregnancy.

On social - emotional measures, foster children in the NSCAW study tended to have more compromised functioning than would be expected from a high - risk sample.43 Moreover, as indicated in the previous section, research suggests that foster children are more likely than nonfoster care children to have insecure or disordered attachments, and the adverse long - term outcomes associated with such attachments.44 Many studies of foster children postulate that a majority have mental health difficulties.45 They have higher rates of depression, poorer social skills, lower adaptive functioning, and more externalizing behavioral problems, such as aggression and impulsivity.46 Additionally, research has documented high levels of mental health service utilization among foster children47 due to both greater mental health needs and greater access to services.
Future research could evaluate the specificity of specialist treatment interventions in larger samples, such as parent training for child behavioural problems, and cognitive or brief psychodynamic therapy for children with post-traumatic stress disorders following exposure to violence.32 Other groups of socially excluded children and families, such as children looked after by local authorities and youth offenders, could also benefit from similar designated, accessible interagency mental health services.
In spite of its relevance for early ages, most research in the area of disruptive problems and attention to emotional information has focused on samples from late childhood and adolescence.
The original research design called for further testing of the instrument with a sample of adolescents receiving treatment for gambling problems.
Moreover, in contrast to a previous report on the present sample (Asscher et al. 2008) which focused on short - term effects (by comparing pre - and posttest scores), in the present study we extend prior research by examining program effects on long term growth in maternal sense of competence, maternal parenting behavior, and child problem behavior over a period of 12 months.
Additional research is needed with larger samples and multiple time - points to further examine the interrelations of sleep problems and comorbidity.
The finding of a linear association between PAE and offspring externalizing problems is consistent with previous research, 49 but the sample may not have included enough children exposed to high levels of prenatal alcohol to explore whether there is a critical threshold.
Because the sample consisted of under aged adolescents with severe behavior problems, the research was reviewed and approved by the relevant medical ethics commission.
Most research on peer relationship problems has used school samples, with relatively little work available on clinical samples of children with ADHD (or any other childhood disorder).
Accumulating evidence, part of which is based on research on parental psychological control and much of which is based on Western samples, has shown that perceived controlling parenting relates to internalizing problems such as depression, low self - esteem and anxiety (e.g., Barber, Stolz, & Olsen, 2005) as well as to externalizing problems, including delinquency, antisocial behavior, and substance use (e.g., Walker - Barnes & Mason, 2004).
