Objective: To examine whether levels of physical activity or sedentary activity are risk factors for the development of depressive symptoms in early adolescence., Methods: A representative sample of 2,464 12- to 15-year-old adolescents living in the middle of Norway was assessed twice, during the years 1998 (T1) and 1999/2000 (T2). The attrition rate was 4.3%. We assessed depressive symptoms (using the Mood and Feelings Questionnaire, MFQ) and levels of physical and sedentary activities at baseline and follow-up. Various potentially confounding factors, including demographic factors, were assessed at baseline., Results: The MFQ scores at T1 were cross-sectionally associated with low levels of vigorous exercise. A possible buffering effect of vigorous exercise on the relationship between stressful life events and depression was demonstrated. In longitudinal analysis low levels of vigorous exercise and high levels of sedentary activities (boys only) predicted a high score (MFQ ≥ 25) at T2., Conclusions: Low levels of vigorous exercise and high levels of sedentary activities (boys only) constituted independent risk factors for the development of a high level of depressive symptoms in a 1-year study of young adolescents. This knowledge should be considered by policy makers, preventative services, and health-care professionals.

The aim of this study was to examine the relationships between being bullied and aggressive behavior and self-reported mental health problems among young adolescents. A representative population sample of 2,464 young Norwegian adolescents (50.8% girls) aged 12-15 years was assessed. Being bullied was measured using three items concerning teasing, exclusion, and physical assault. Self-esteem was assessed by Harter's self-perception profile for adolescents. Emotional and behavioral problems were measured by the Moods and Feelings Questionnaire (MFQ) and the youth self-report (YSR). Aggressive behavior was measured by four items from the YSR. One-tenth of the adolescents reported being bullied, and 5% reported having been aggressive toward others during the past 6 months. More of the students being bullied and students being aggressive toward others reported parental divorce, and they showed higher scores on all YSR subscales and on the MFQ questions, and lower scores on the global self-worth subscale (Harter) than students not being bullied or aggressive. A few differences emerged between the two groups being bullied or being aggressive toward others: those who were aggressive showed higher total YSR scores, higher aggression and delinquency scores, and lower social problems scores, and reported higher scores on the social acceptance subscale (Harter) than bullied students. However, because social problems were demonstrated in both the involved groups, interventions designed to improve social competence and interaction skills should be integrated in antibullying programs.

Aims: Knowledge of sleep problems and their relationships among adolescent psychiatric patients is limited. This study investigated whether adolescents in specialty mental health care differ in rate and correlates of sleep problems from adolescents in a community sample; 2465 adolescents from a community sample were compared with a representative clinical sample of 129 adolescent patients., Methods: Comparisons were made on frequent sleep problems according to scores on the Youth Self-Report, the Mood and Feelings Questionnaire, and instruments assessing coping styles, stresses and family functioning., Results: Sleep problems were more frequent in the clinical sample than the community sample (31.3% vs. 5%). Sleeping little and being overtired were the most common sleep problems. Sleep problems were multivariately associated with internalizing problems in both samples. Poor family functioning and distractive coping were multivariately associated with sleep problems among adolescent patients, whereas depressive symptoms were multivariately associated in community adolescents., Conclusions: Prevalences of sleep problems were high among adolescent patients. However, sleep problems may be in danger of being unnoticed in clinical practice. Clinicians should ask about such problems and be aware of possible connections with family functioning, depression and suicidality. Therapeutic interventions directed towards sleep problems should be considered.

Objective: To examine the role of depressive symptoms and disorders as associates and predictors of suicidal acts across adolescence., Method: A representative sample of Norwegian school students (N = 2464, mean age 13.7 years) in grades 8 and 9 was reassessed after one year (T2) with the same questionnaire. All high scorers of depressive symptoms on the Mood and Feelings Questionnaire (MFQ) at T2 were defined as cases. One control from low or middle scorers, matched for age and gender, was randomly assigned to every two cases. This subset (n = 345) was diagnostically assessed by face-to-face K-SADS-PL interviews (mean age = 14.9 years). The same subset was reassessed after 5 years (T3) by using the same questionnaire (n = 252, mean age = 20.0 years) and telephone K-SADS-PL interviews (n = 242). The participation rate was 76.9% (n = 265)., Results: Cognitive symptoms dominated the depressive symptom profile among suicide attempters, irrespective of age and time. Among younger adolescents, suicidal thoughts and acts of self-harm without suicidal intent were associated with suicidal acts. Recurrent thoughts about death, hopelessness, disturbed concentration and middle insomnia were associates of suicidal acts among older adolescents. Worthlessness by 15 years was a significant predictor of suicidal acts between 15 to 20 years. MDD and a depressive episode, not otherwise specified, continued to be significant associates among younger adolescents, while dysthymia by 15 years remained a predictor of suicidal acts between 15 to 20 years, even when controlled for depressive symptoms., Conclusions: Self-harm without suicidal intent, middle insomnia, cognitive depressive symptoms and a formal psychiatric diagnosis of any depressive disorder should alert professionals in the risk assessment of suicidal adolescents.

In a representative sample of 2,464 Norwegian adolescents, aged 12-15 years, 7.8% (n= 191) reported reading difficulties (RD). No gender difference was found. Adolescents with RD were compared to classmates on psychosocial variables. In univariate analysis, RD adolescents report higher levels of depressive symptoms, more school stress, worried more about going to school, had lower school grades and lower attachment to parents than those without RD. They also scored lower on Global Self-worth and on Social Acceptance scales. Further, they reported reduced levels of psycho-functioning during the previous year because of mental health problems, they had received more help and had used more medication for such problems. In a multivariate logistic regression analysis, receiving help for mental health problems and reduced psycho-functioning showed the strongest associations with student RD status. No gender interactions were found. The study demonstrated important differences between adolescents with and without RD.

Objective: To examine the influences of familial, peer and individual predictors of suicidal acts in a longitudinal study with a subset of school adolescents reporting high levels of depressive symptoms., Method: A representative sample of Norwegian school students (N=2464, mean age 13.7 years, T1) was reassessed after 1 year (T2) with the same questionnaire. All high scorers of depressive symptoms on the Mood and Feelings Questionnaire (MFQ) at T2 were defined as cases. One control from low or middle scorers, matched for age and gender, was randomly assigned to every two cases. This subset (n=345) was diagnostically assessed by face-to-face K-SADS-PL interviews (mean age=14.9 years). The same subset was reassessed after 5 years (T3) by using the same questionnaire (n=252, mean age=20.0 years) and telephone K-SADS-PL interviews (n=242). The participation rate at T3 was 76.9% (n=265). The questionnaire explored various relationships with family members, peers and individual factors such as lifestyle habits, and physical health., Results: Irrespective of time, history of a suicidal act significantly predicted a later suicidal act. Not living with both biological parents and a diagnosis of any depressive disorder were significant predictors for younger and older adolescents, respectively., Conclusions: In line with the findings of previous clinical studies, our results underline the importance of identifying previous suicidal acts, depressive disorders, broken homes and risk behaviours such as smoking and intoxication in the assessment of suicidal risk across adolescence.

In this survey of early Norwegian school adolescents, the prevalence, course, and incidence of self-harm behavior with or without suicide intent were examined, in addition to predictors of self-harm for a 1-year follow-up period. Lifetime prevalence rates of self-harm without suicide intent and suicide attempts were 2.9% and 3.0%, respectively, while 1-year incidence rates were 3.6% and 1.7%, respectively. In multivariate analysis, five predictors significantly differentiated self-harmers from non-self-harming adolescents. Early school adolescents having frequent or intense suicidal ideation over an extended time period and attempting self-harm repeatedly with or without suicide intent should be identified and offered treatment.

In a one-year longitudinal study, emotional/behavioural correlates and predictors of four common pain complaints (headaches, stomach, back and limb pain), were examined in a representative school sample of 2360 adolescents aged 12- to 15-years. At first assessment, 18.3% reported being bothered by a frequent pain (at least once a week) and 40% of the pain sufferers had two or more pain locations, more commonly reported by girls. Subjects having any of the four frequent pains reported having fewer friends and were more often absent from school. Frequency and number of reported pains among adolescents were positively related to levels of internalising and externalising problems. These latter problems were consistently and significantly higher among adolescents with frequent back and limb pains, however, when coexistence of another frequent pain was controlled, differences were small. Number of pains at the one-year follow-up was significantly predicted by frequent back pain and headache, depressive symptoms scores, somatic complaints (other than pain), number of friends and reduced leisure time activities during the follow-up period. Frequent back pain and depressive symptoms also predicted multiple frequent pains (vs single frequent pain) at the follow-up as did recent parental divorce. It is concluded that various emotional and behavioural problems, and which are commonly regarded as being specifically related to pain type or location among adolescents, depend rather on frequency and coexistence of multiple frequent pains. Assessment of adolescents with frequent and multiple pains should, therefore, include broad screening of internalising as well as externalising problems as well as various aspects of impairment.

Background: The study investigates whether adolescents referred to specialty mental health services from local services differ from adolescents who only have received help for psychiatric problems locally. If so, which factors associate strongest with referral?, Method: Adolescents (n = 76) from an adolescent population sample (N = 2,538) who had received help during the last year for mental problems from local services were compared to a clinical sample of adolescents (N = 129) referred to specialty mental health services from such local services. Comparisons were made according to scores on the Youth Self-Report (YSR); depressive symptoms; family functioning; attachment to parents; self-concept; coping styles; response styles; dysfunctional attitudes; negative life events; daily hassles; socio-demographics., Results: As compared to adolescents receiving help locally, adolescents in specialty mental health care scored higher on YSR internalising syndrome; YSR attention problems; YSR thought problems; suicidality; psychosocial stressors; knowing someone who had attempted suicide; parental divorce; substance use; recent moves; living in lodgings; lost a pal or boy/girlfriend; and lower on attachment to parents. Multivariate logistic regression analysis identified four factors associated with receiving specialty mental health care: low family functioning; moved previous year; knowing someone who had attempted suicide; own suicidality., Conclusions: Family functioning as reported by the adolescents, and not mental health problems except for suicidality, was found to be the strongest associated with referral to specialty mental health services. Contrary to findings from many other studies, referral was associated with internalising problems, not externalising ones.

The aims of this study were to examine correlates of self-reported depressive symptoms within the school area, and possible predictors of change in depressive symptom levels over a 1-year period in a large representative sample of 12 to 15-year-old adolescents in central Norway. The school variables were: school stress, class wellbeing, teacher support, and grades. Possible confounding factors were age, SES, ethnicity, and parental divorce. We also examined the strengths of these relationships. In the cross-sectional multivariate analyses of the whole sample, at time-point one (T1), all four school factors were independently associated with depressive symptom levels at small to moderate levels. In the longitudinal multivariate analyses of the whole sample, self-reported depressive symptom levels at time-point two (T2) were predicted by depressive symptom levels at T1, gender and teacher support. For girls, three of the school variables significantly predicted depressive symptom levels at T2, while this was not the case for boys. Prevention in schools might be of importance.

Objective: To examine the prevalence rate, course, annual incidence, and predictors of frequent headaches (at least once a week) in a 1-year longitudinal study of a representative school sample of 2355 adolescents aged 12 to 14 years., Methods: Information was gathered by means of questionnaires administered to the subjects at school., Results: The overall prevalence estimates of frequent headaches, including those subjects reporting another type of frequent pain, were 8.1% and 8.9% at the two assessment points (T(1) and T(2)), and 3.3% to 4% for frequent headaches without other frequent pain complaints. Both forms of frequent headaches were about three times more common among girls than boys. Persistence of frequent headaches (with possible pain comorbidity) was high, in that more than one-third of adolescents reporting frequent headaches continued to have such headaches 1 year later. Persistence also increased with age, in particular among 13- to 14-year-old girls. The overall annual incidence of frequent headaches in the whole sample was 6.5%. While incidence was about twice as high among adolescent girls than boys, there was a steady increase among girls, whereas the rates were stable in boys. The results of multivariate regression analyses showed that frequent headaches at 1-year follow-up could be significantly predicted by frequent headaches at first assessment, impairment (reduced leisure time activities), and high depressive symptom scores, in addition to gender (girls had a worse outcome)., Conclusions: Frequent headaches, among girls in early adolescence in particular, should be carefully evaluated, and treatment offered to those who are impaired in their daily life functioning.

The objectives of the study were to describe monthly variations in issues in calls to a help-line for children and adolescents. All 80,983 calls to a Red Cross Help-Line for children in 1991-1997 were included. In 22,698 calls, information about age, sex or issue could be identified. A monthly variation in frequency of calls with peaks in April and November and a correlation with the absolute values of monthly changes in length of day were found. Conversations concerning psychiatric suffering were more frequent in January or February and less frequent than expected in May/June and December. Conversations about sexuality correlated with the frequencies of births in the adult population 9 months later. A spring and fall peak in total calling and a winter peak in calls for depression, anxiety, pain and neglect were described.

Background: The aim of the study was to examine the relationships between various psychosocial factors and depressive symptoms in early adolescence., Methods: A representative sample of 2,465 12-14-year-old adolescents comprising 50.8% girls and 49.2% boys, with a mean age of 13.7 years, was recruited in two counties in Norway. The participation rate was 88.3%. Depressive symptoms were measured by the Mood and Feelings Questionnaire (MFQ)., Results: Correlations between the total sum of stressful events/daily hassles and the total sum of MFQ were moderately high, rs = .49 and rs = .53, respectively. Depressive symptoms were more strongly correlated with school-related stress among boys than girls, whereas the correlation between daily hassles and depressive symptoms was higher for girls than boys. The results of univariate analyses showed significantly higher mean total MFQ scores among adolescents not living with both natural parents, those who had moved more than twice and those with more than 3 siblings orhaving fewer than 2 close friends. Further, adolescents from Third World societies and adopted adolescents, those from lower SES groups, having unemployed parents or living in coastal areas had higher mean depressive symptom scores. The results of multiple regression analyses yielded the following six significant predictors of total MFQ scores in order of importance: Sum of daily hassles and sum of stressful life events, gender, number of friends, ethnicity and mother's employment status. Altogether, these variables accounted for 43% of the total variance in MFQ scores., Conclusions: It is concluded that these psychosocial predictors should be addressed when assessing depressive symptoms in early adolescence. The findings of the study are discussed in view of previous research in the field and their clinical significance.

Objective: To investigate whether insecure attachment is a predictor of subsequent depressive symptoms among adolescents 12-14 years of age, when controlled for depressive levels the preceding year, various demographic and psychosocial factors, and stressful life events., Method: A representative sample of 2,360 young adolescents was assessed at two time points 1 year apart. Measures included were depressive symptoms measured by the Mood and Feelings Questionnaire (MFQ), attachment to parents and friends measured by the Inventory of Parent and Peer Attachment, stressful events, and various sociodemographic factors. The initial response rate was 88.3% and the attrition rate was 4.3%., Results: The proportions of high scorers (MFQ > 33) increased threefold from T1 to T2 (3.4% to 10.9%). Results of multivariate logistic regression analyses showed that the following variables at T1 were predictive of depressive symptoms at T2 : severe depressive symptoms (odds ratio [OR] = 5.30), gender (OR = 4.08), attachment to parents (OR = 1.36), and stressful life events (OR = 1.12). No interactions between attachment and severe depressive symptoms and gender and stressful life events, respectively, were found., Conclusions: Insecure attachment to parents may contribute to the development of severe depressive symptoms among young adolescents. Improving the adolescent-parent relationship could be a focus for interventions both in community services and in clinical work.

Background: To investigate seasonal variations in telephone calls to a help-line for children, and their correlation to changes in length of day, latitude and age., Method: 691,787 calls to the Red Cross Help-Line in Norway for children in the three-year period 1996-1998 were included., Results: Monthly frequencies of calls deviated significantly from an expected even distribution (chi2=9446.34, df=11, P<0.0001). The frequency curve for calls peaked in April and October and had its lowest level in July and December. Variation was pronounced: the mean number of daily calls varied between 436 in July and 886 in April. There was a strong and positive correlation between the number of calls and the change in length of day across the year (r(s)=0.76, N=12, P<0.01). Increasing latitude correlated positively with the range of the monthly observed/expected ratios of calls (r(s)=0.79, N=7, P<0.05). The frequency of calls was largest among children 12 to 14 years of age. Age correlated negatively with the range of monthly observed/expected ratios of calls (r=-0.94, N=12, P<0.001)., Limitations: Social and cultural factors could not be explored in the design used in the present study., Conclusions: The frequency of calls from children correlates positively with change in length of day (i.e., maximal in spring and fall), and the magnitude of the seasonal variation correlates positively with latitude and negatively with age. Knowledge of seasonal variation in requests for help may have value in planning services for children.

The purpose of the present study was to examine growth in children on extended stimulant treatment. Ninety-one hyperactive boys were studied, of whom 68 were treated with amphetamine and 23 with methylphenidate. The age range was 3-10 years. All children were treated with one of these stimulants for a minimum of 1 year. The yearly mean values for height and weight were all between the 25th and 90th percentile of the population norms. During the 1st year of treatment children who used amphetamine showed significantly smaller weight gains than those who used methylphenidate (F = 6.9, df = 64, P < 0.05). Four patients (17%) in the methylphenidate group and 21 (31%) in the amphetamine group had a weight loss during the 1st year, ranging from 0 to 9.5 kg. Within this group of 25 patients there was a significantly higher number of children with a pretreatment weight greater than that of the 50th percentile group (chi-square = 5.59, P < 0.05). All 25 patients showed sufficient weight gain at later examinations. Multiple regression analyses showed that neither cumulative doses nor age had a significant effect on growth when initial weight and height were controlled for. These findings indicate that, for most children, extended treatments with amphetamine or methylphenidate do not have negative effects on growth. However, some children show weight loss during the 1st year of treatment, more often when amphetamine is used. Among those children who may show reduced weight gain, most are above mean weight before treatment begins.
