RESUMO
BACKGROUND: As patient-centered care gains more attention, assessing the patient's perspective on their recovery has become increasingly important. In response to the need for a reliable and valid patient reported outcome measurement tool for major surgical resections in Norway. The Norwegian Registry for Gastrointestinal Surgery (NORGAST) initiated a project to translate and evaluate QoR-15's psychometric properties for patients going through general, gastrointestinal (GI), and hepato-pancreato-biliary (HPB) resectional surgery. METHODS: After a translation and adaption of the original version of QoR-15 into Norwegian, the QoR-15NO was psychometrically evaluated including a confirmatory factor analysis to test for unidimensionality, as well as tests for content validity, internal consistency, measurement error, construct validity, feasibility, and responsiveness. This process included cognitive interviews using a structured interview guide. Further, patients who underwent various types of GI/HPB surgery at five hospitals in different parts of Norway completed the QoR-15NO before surgery and on the first or second day after surgery. The impact of surgery was classified according to Surgical Outcome Risk Tool v2 (SORT), in extra major/complex, major, intermediate, and minor. RESULTS: This study included 324 patients with 83% return rate with both pre- and postoperative forms. There were negative correlations between duration of surgery and postoperative QoR-15 score and the difference between post- and preoperative score (change score). Individuals who had gone through surgery with major impact had a lower postoperative mean QoR-15 score (97) than their counterparts who had experienced either medium (QoR-15: 110) or minor (QoR15: 119) impact surgery. Cronbach's alpha (0.88) and Omega Alpha Total (ωt = 0.90) indicate that the scale has good to very good internal consistency. Test-retest reliability was measured by Intra-class Correlation Coefficient to ICC = 0.70. Confirmatory factor analyses supported that a one-factor model with correlated residuals had a good fit to data. CONCLUSION: This study supports QoR-15NO as a valid, essentially unidimensional, feasible, and responsive instrument among patients undergoing general, GI, and HPB resectional surgery in Norway. The total QoR-15NO score provides important information that can be used in an everyday clinical setting and integrated into NORGAST.

BACKGROUND: The aim of the present study was to examine the factor structure and reliability of a six-item scale of rule-breaking behaviour, and to test for measurement invariance across gender, age, survey year and geographical location. METHODS: Data were from three yearly cross-sectional and population-based collections of the Ungdata surveys (2017 to 2019) including a total of 297,102 Norwegian adolescents aged approximately 13 to 19 years. Measurements included respondent's rule-breaking behaviour, time, gender, age and geographical location. RESULTS: Confirmatory factor analyses demonstrated that a one-factor solution of the rule-breaking behaviour scale had good fit to data (comparative fit index 0.98; Tucker-Lewis index 0.96; root mean square error of approximation 0.049 (95% confidence interval 0.048, 0.050)), with factor loadings ranging from 0.60 to 0.81 for all items (mean factor loading 0.72). Similar results were found across survey years for both genders. Several multiple group confirmatory factor analyses showed indications of measurement invariance for the scale across gender, age groups, geographical locations and survey years. The ordinal alpha and omega coefficients for internal consistency of the scale were both 0.86. CONCLUSIONS: The six-item scale for self-reported rule-breaking behaviour demonstrated good psychometric properties and appears to constitute a reliable measure of adolescent rule-breaking behaviour for use in population-based surveys in a Norwegian setting.

BACKGROUND: There is compelling evidence for an association between negative life events (NLE) and substance-related problems (SRP) during adolescence. The literature is, however, still limited with regards to protective factors for SRP among adolescents exposed to NLE. METHODS: A large population-based survey including 9,611 Norwegian adolescents aged 16 to 19 years, comprised the dataset of this study. The main explanatory variable was NLE. The main outcome variable was SRP, assessed by the CRAFFT scale. Potential protective factors were measured with five subscales from the Resilience Scale for Adolescents (READ) questionnaire. The potential protective factors and sex were explored as moderators for the associations between NLE and SRP. RESULTS: NLE were strongly associated with SRP. Four out of five potential protective factors (i.e., Goal Orientation, Self-confidence, Family Cohesion, and Social Support) showed evidence of a protective-stabilizing effect. Even if they had protective effect across all levels of exposure to NLE, these effects were even stronger for adolescents with high exposure. For Family Cohesion a protective-stabilizing effect was only evident for boys, while a direct protective effect was found for girls. Finally, Social Competence was the only factor that did not show any evidence of promoting resilience toward SRP. CONCLUSIONS: NLE had a strong relation with SRP in this study. Protective factors buffered against SRP for all adolescents - but particularly so for adolescents who had high exposure to NLE. These findings highlight the need for preventive efforts to strengthen protective factors that may promote resilience among adolescents at risk for SRP.

BACKGROUND: Little is known about self-reported health in octogenarians (≥80 years) and nonagenarians (≥90 years) following percutaneous coronary intervention (PCI), including characteristics of different health outcomes. This study aimed to phenotype latent health profiles of self-reported health in older adults 2 months post-PCI. METHODS: A prospective, multicentre, real-world study (CONCARDPCI) of 270 octogenarians and nonagenarians was performed with five validated and standardised measures of self-reported health at 2 months post-PCI. Latent profile analysis was used to identify health profiles, and multinomial logistic regression analyses were used to investigate the associations between patient characteristics and health profiles. RESULTS: Three latent health profiles were identified: The Poor health profile included 29%, the Moderate health profile included 39%, and the Good health profile included 32% of the participants. Older adults who were frail (OR 2.50, 95% CI 1.17-5.33), had a low exercise level (OR 0.49, 95% CI 0.39-0.95), and low alcohol intake (OR 0.61, 95% CI 0.39-0.95) were more likely to belong to the Poor health profile relative to the Good health profile. Furthermore, older age (OR 1.19, 95% CI 1.03-1.37) and lower exercise level (OR 0.64, 95% CI 0.43-0.97) were associated with belonging to the Moderate health profile relative to the Good health profile. CONCLUSION: Two months after PCI, most participants displayed having Moderate to Good health profiles. Those with a Poor health profile were more likely to be frail and less active. These findings highlight that follow-up care has to be patient-centred and tailored to improve the health status of older adults.

BACKGROUND: The RAND-36 and RAND-12 (equivalent to versions 1 of the SF-36 Health Survey and SF-12 Health Survey, respectively) are widely used measures of health-related quality of life. However, there are diverging views regarding how to create the physical health and mental health composite scores of these questionnaires. We present a simple approach using an unweighted linear combination of subscale scores for constructing composite scores for physical and mental health that assumes these scores should be free to correlate. The aim of this study was to investigate the criterion validity and convergent validity of these scores. METHODS: We investigated oblique and unweighted RAND-36/12 composite scores from a random sample of the general Norwegian population (N = 2107). Criterion validity was tested by examining the correlation between unweighted composite scores and weighted scores derived from oblique principal component analysis. Convergent validity was examined by analysing the associations between the different composite scores, age, gender, body mass index, physical activity, rheumatic disease, and depression. RESULTS: The correlations between the composite scores derived by the two methods were substantial (r = 0.97 to 0.99) for both the RAND-36 and RAND-12. The effect sizes of the associations between the oblique versus the unweighted composite scores and other variables had comparable magnitudes. CONCLUSION: The unweighted RAND-36 and RAND-12 composite scores demonstrated satisfactory criterion validity and convergent validity. This suggests that if the physical and mental composite scores are free to be correlated, the calculation of these composite scores can be kept simple.

Due to the rapid development of nanotechnology and its integration into dentistry, there is a need for information on the factors influencing the decision of dental health-care workers to use nanomaterials. Based on a national survey among Norwegian dentists and dental hygienists, this study applied the theory of planned behavior (TPB), augmented with past behavior and perceived risk, to predict the intention to use dental nanomaterials in the future and to assess whether an augmented TPB model operates equivalently across professional groups. Structural equation modelling was used to assess whether the hypothesized model fits the data. Of 1792 eligible participants, 851 responded to an electronic survey. Attitudes and perceived behavioral control had the strongest effect on intention, followed by past behavior and subjective norms. Risk perceptions had an indirect effect on intention. Multigroup comparison confirmed invariance of the model across professional groups. This study supports the validity of the augmented TPB model to explain the intention of Norwegian dentists and dental hygienists to use nanomaterials. The strongest influence on intention is given by the attitudes toward nanomaterials and perceived confidence in their use. The findings of the study have implications for management of the use of nanomaterials in dentistry by policy makers.

The effectiveness of bullying prevention programs has led to expectations that these programs could have effects beyond their primary goals. By reducing the number of victims and perpetrators and the harm experienced by those affected, programs may have longer-term effects on individual school performance and prevent crime. In this paper, we use Norwegian register data to study the long-term impact of the Olweus Bullying Prevention Program (OBPP) on academic performance, high school dropout, and youth crime for the average student, which we call population-level effects. The OBPP program is widely acknowledged as one of the most successful programs reducing school-level bullying; yet, using a difference-in-difference design, no statistically significant population-level effects of the OBPP were found on any of the long-term outcomes in this study. When studied at the population level, as in the current project, the base rate prevalence of bullying is a major explanatory factor for these results. Earlier studies have shown that OBPP reduces bullying prevalence by 30-50%. This decrease translates into absolute reductions in bullying victimization and perpetration at the population level of "only" four and two percentage points, respectively. Our results suggest the average causal effects of school bullying involvement are too small to translate this reduction in bullying into a sizeable population-level impact on students' long-term outcomes. However, a limited potential of anti-bullying programs to prevent population-level adversity can very well be compatible with substantial program effects for individual bullies and victims. Further, our results do not speak to the main objective of anti-bullying programs of limiting childhood abuse and safeguarding children's human rights.

Aims: The structure of adolescents' families has become more complex over the last decades in several western countries. In parallel, health complaints among adolescents appear to have risen in the Nordic countries. This study aimed to examine the association between family structure and health complaints among Norwegian adolescents while capturing biological, half-, and stepsiblings (sibship-type) in the families. Methods: Data stem from the youth@hordaland study, an epidemiological study of adolescents aged 16-19 years (N = 10,257; participation rate = 53%) conducted in 2012. This study is based on a subsample of 8808 adolescents who lived with parent(s). The adolescents provided detailed information on sociodemographics, family structure, sibship-type, and common health complaints among youth (headache, dizziness, and abdominal, neck, back, and shoulder pain). Results: Adolescents in nuclear families and joint physical custody (JPC) reported significantly lower levels of health complaints compared to peers in single- or stepparent families. Independent of family structure, biological siblings were associated with lower levels of health complaints, while stepsiblings were associated with higher levels of health complaints, but only among girls. These findings were robust to adjustments of sociodemographic variables. Conclusions: Health complaints are frequent but unequally distributed across family structures. Adolescents in nuclear families and JPC report lower levels of health complaints compared to peers in single- or stepparent families. Considering siblings appears to be relevant, as biological- and stepsiblings were related to adolescents' symptoms, independent of family structure. In combination, knowledge about family structure and sibship-type may aid the identification of adolescents at risk of experiencing health complaints.

PURPOSE: Evidence is emerging on the importance of psychological readiness to return to sport after anterior cruciate ligament (ACL) reconstruction. The ACL-Return to Sport after Injury scale (ACL-RSI) is developed to assess this. The aim of the current study was to translate ACL-RSI into Norwegian and examine the measurement properties of the Norwegian version (ACL-RSI-No). METHODS: ACL-RSI was translated according to international guidelines. A cohort of 197 ACL-reconstructed patients completed ACL-RSI-No and related questionnaires nine months post-surgery. One hundred and forty-six patients completed hop tests and 142 patients completed strength tests. Face and structural validity (confirmative factor analysis and explorative analyses), internal consistency [Cronbach's alpha (α)], test-retest reliability [Intraclass Correlation Coefficients (ICC)], measurement error [Standard error of measurement (SEM) and smallest detectable change at individual (SDCind) and group level (SDCgroup)] and construct validity (hypotheses testing; independent t tests, Pearson's r) were examined. RESULTS: ACL-RSI-No had good face validity. Factor analyses suggested that the use of a sum score is reasonable. Internal consistency and test-retest reliability were good (α 0.95, ICC 0.94 (95% CI 0.84-0.97) and measurement error low (SEM 5.7). SDCind was 15.8 points and SDCgroup was 2.0. Six of seven hypotheses were confirmed. CONCLUSIONS: ACL-RSI-No displayed good measurement properties. Factor analyses suggested one underlying explanatory factor for "psychological readiness"-supporting the use of a single sum score. ACL-RSI-No can be used in the evaluation of psychological readiness to return to sport after ACL injury. LEVEL OF EVIDENCE: III.

In agreement with two predictions, this somewhat unusual study documented that 70 elementary schools (A-schools) with continued and repeated use of the Olweus Bullying Questionnaire (OBQ) in a four-year follow-up period of 2007-2010, two to eight years after original implementation of the Olweus Bullying Prevention Program (OBPP), had a clearly more favorable long-term development in terms of being-bullied problems, as measured with a completely independent data source, the National Pupil Survey than 102 comparable schools (B-schools) that had not conducted any OBQ-surveys in the same period. The odds of being bullied for students in a Norwegian average elementary school were also almost 40% higher than for students who attended a school with continued use of the OBQ, and very likely, other components of the program. Several alternative explanations of the findings were explored and found wanting. Results suggested that A-schools with continued use had changed their "school culture" for the better with regard to awareness, preparedness and competence in handling and preventing bullying. This form of 'organizational learning' has major consequences in that new groups of students will benefit from such a school environment. It was generally concluded - in spite of a highly stable average of the level of bullying problems in Norway - that it is fully possible to substantially reduce such problems not only in one-year evaluations, as has been amply documented before, but also in the long term, up to eight years after original implementation, with a program such as the Olweus Bullying Prevention Program.

BACKGROUND: This study provides an empirical test of the reasoned action approach (RAA) socio-cognitive theory with the aim of 1) predicting the intention of public dental health personnel (PDHP) to report suspected child-maltreatment to child welfare services (CWS); 2) estimating the effects of the theoretical constructs of RAA, including experiential and instrumental attitudes, injunctive and descriptive norms, and perceived capacity and autonomy regarding PDHP's behavioural intentions; and 3) exploring whether the RAA operates equivalently (i.e., is invariant) in male and female providers. METHODS: This national cross-sectional study was conducted in Norway. An electronic survey was distributed to 1542 dentists and dental hygienists working in the public dental health service. The survey included RAA items constructed in accordance with the recommendations for the RAA model. Structural equation modelling (SEM) was used to identify factors derived from the theory of RAA to predict PDHP reporting intentions. RESULTS: A total of 77.8% (1200) of those surveyed responded to the survey. The present study provided support for the utility of the RAA across both male and female providers in predicting their intention to report suspected child-maltreatment to the CWS. The final modified SEM model revealed that instrumental attitudes and perceived behavioural control (based on merged capacity and autonomy parameters) were the strongest predictors of intention to report, followed by the reporting of descriptive norms, injunctive norms and experiential attitudes. These factors explained 63.6% of the observed variance in the reporting intention. CONCLUSIONS: The large amount of explained variance suggests that RAA is a well-functioning theory that predicts PDHP's reporting intentions to CWS across gender, and gives an understanding of the socio-cognitive factors involved. To strengthen reporting intention among dental personnel, this study suggests educators should focus on the value and positive consequences of reporting, the resources available and how to overcome obstacles; attention to normative expectations and individuals' feelings about reporting may also be helpful.

BACKGROUND: The 7-item Game Addiction Scale (GAS) has been validated under standard confirmatory factor analysis and exhibits good psychometric properties. Whether this scale satisfies the necessary conditions for consideration by item response theory (IRT) modeling remains unknown. However, the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) recently proposed criteria, in its section 3, to define internet gaming disorder (IGD) to promote research on this possible condition. OBJECTIVE: The objective of our study was to (1) analyze GAS in the context of IRT (graded-response) modeling; (2) investigate differential item functioning (DIF), a feature of IRT modeling, in 2 subsamples; and (3) contribute to the ongoing (IGD) debate related to the validity of the DSM-5 criteria using GAS items as a proxy. METHODS: We assessed 2 large representative samples of Swiss men (3320 French-speaking and 2670 German-speaking) with GAS. RESULTS: All items comprised high discrimination parameters. GAS items such as relapse, conflict, withdrawal, and problems (loss of interests) were endorsed more frequently in more severe IGD stages, whereas items related to tolerance, salience (preoccupation), and mood modification (escape) were endorsed more widely among participants (including in less severe IGD stages). Several DIF effects were found but were classified as negligible. CONCLUSIONS: The results of the analyses partly support the relevance of using IRT to further establish the psychometric properties of the GAS items. This study contributes to testing the validity of the IGD criteria, although cautious generalization of our findings is required with GAS being only a proxy of the IGD criteria.

BACKGROUND: Long-term sick leave and withdrawal from working life is a concern in western countries. In Norway, comprehensive inpatient work rehabilitation may be offered to sick listed individuals at risk of long-term absence from work. Knowledge about prognostic factors for work outcomes after long-term sick leave and work rehabilitation is still limited. The aim of this study was to test a mediation model for various hypothesized biopsychosocial predictors of continued sick leave after inpatient work rehabilitation. METHODS: One thousand one hundred fifty-five participants on long-term sick leave from eight different work rehabilitation clinics answered comprehensive questionnaires at arrival to the clinic, and were followed with official register data on sickness benefits for 3 years. Structural equation models were conducted, with days on sickness benefits after work rehabilitation as the outcome. RESULTS: Fear avoidance beliefs for work mediated the relation between both musculoskeletal complaints and education on days on sickness benefits after work rehabilitation. The relation between musculoskeletal complaints and fear avoidance beliefs for work was furthermore fully mediated by poor physical function. Previous sick leave had a strong independent effect on continued sick leave after work rehabilitation. Fear avoidance beliefs for work did not mediate the small effect of pseudoneurological complaints on continued sick leave. Poor coping/interaction ability was neither related to continued sick leave nor fear avoidance beliefs for work. CONCLUSIONS: The mediation model was partly supported by the data, and provides some possible new insight into how fear avoidance beliefs for work and functional ability may intervene with subjective health complaints and days on sickness benefits after work rehabilitation.

This review examined child sexual abuse in the Nordic countries focusing on prevalence rates and victims' age and relationship to the perpetrator. The results show a prevalence of child sexual abuse (broadly defined) between 3-23% for boys and 11-36% for girls. The prevalence rates for contact abuse were 1-12% for boys and 6-30% for girls, while 0.3-6.8% of the boys and 1.1-13.5% of the girls reported penetrating abuse. The findings suggest an increased risk of abuse from early adolescence. In adolescence, peers may constitute the largest group of perpetrators. The results highlight the need for preventive efforts also targeting peer abuse. Future research should include cross-national and repeated studies using comparable methodology.

In the present article, we used IRT (graded response) modeling as a useful technology for a detailed and refined study of the psychometric properties of the various items of the Olweus Bullying scale and the scale itself. The sample consisted of a very large number of Norwegian 4th-10th grade students (n = 48 926). The IRT analyses revealed that the scale was essentially unidimensional and had excellent reliability in the upper ranges of the latent bullying tendency trait, as intended and desired. Gender DIF effects were identified with regard to girls' use of indirect bullying by social exclusion and boys' use of physical bullying by hitting and kicking but these effects were small and worked in opposite directions, having negligible effects at the scale level. Also scale scores adjusted for DIF effects differed very little from non-adjusted scores. In conclusion, the empirical data were well characterized by the chosen IRT model and the Olweus Bullying scale was considered well suited for the conduct of fair and reliable comparisons involving different gender-age groups.

Having a distant relationship with parents seems to increase the risk of developing a more negative global self-esteem. This article describes a longitudinal study of 1,090 Norwegian adolescents from the age of 13-23 (54 % males) that explored whether peer acceptance can act as a moderator and protect global self-esteem against the negative effects of experiencing low closeness in relationships with parents. A quadratic latent growth curve for global self-esteem with closeness to parents and peer acceptance as time-varying covariates was modeled, taking partial measurement invariance in global self-esteem into account. Peer acceptance was found to have a general protective effect on global self-esteem for all adolescents. In addition, at most ages, peer acceptance was found to have a protective-stabilizing effect on the relationship between closeness to parents and global self-esteem. This indicates that peer acceptance can be an especially valuable source of global self-esteem when closeness to parents is low.

The Childhood Trauma Questionnaire--Short Form (CTQ-SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out-of-home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five-factor structure of the CTQ-SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ-SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma.

The rising rates of physical and mental health complaints among adolescents observed in many countries have coincided with an increased time spent on screen-based devices, including social media use. We sought to document recent trends in physical health complaints (PHC) and whether co-occurring trends in screen time, social media use, and physical activity may account for these trends. To achieve these aims, we used data from the nationwide Ungdata surveys conducted annually at the municipality level in Norway, comprising 419,934 adolescents aged 13-18 from six survey years (2014-2019). Six items assessed PHC, including neck and shoulder pain, headache, and abdominal pain, during the past month. To account for the nesting structure of Ungdata, and to exploit the variation within and between municipalities, we used multilevel analyses with adolescents nested in municipality-years (n = 669), nested in municipalities (n = 345). We found a small to moderate linear increase in number of PHC among boys and girls from 2014 to 2019. Screen time and social media use moderately attenuated the trend for girls, and to a lesser extent for boys. Screen time and social media use were further positively associated with PHC across the between and within-municipality levels, and social media use was more strongly associated with PHC for girls than boys across all levels of analysis. A similar pattern emerged when considering each symptom individually. The results suggest that the prevalence of PHC rose in tandem with a group-level shift towards higher screen time and social media use. Moreover, the results indicate that higher screen time and social media use may have led to changes in the youth culture with potential consequences for adolescents' well-being.
RESUMO
OBJECTIVE: To examine whether a bifactor model with a general ADHD factor and domain specific factors of inattention, hyperactivity and impulsivity was supported in a large general population sample of children. We also explored the utility of forming subscales based on the domain-specific factors. METHODS: Child mental health questionnaires were completed by both teachers and parents of all children in grades 2-4 in Bergen, Norway. Confirmatory factor analysis was performed on the ADHD items of a modified version of the Swanson, Nolan and Pelham Questionnaire-IV (SNAP-IV) for 6,237 children. RESULTS: The bifactor model showed very good model fit with a strong general ADHD factor and specific factors for impulsivity and inattention. The subfactors, especially hyperactivity, generated from the SNAP-IV ADHD items conveyed little unique variance in the model. CONCLUSIONS: The findings in this general population sample with a strong general ADHD factor in the bifactor model supports the view on ADHD as a unitary concept with specific domain factors for inattention and impulsivity, but not for hyperactivity. The bifactor model questions the utility of constructing ADHD subscales by the use of a simple sum score when using the SNAP-IV.

Background: Sexual- and gendered harassment are normalised in many peer groups, yet their associations with mental health concerns among adolescents are well-established. School based interventions that prevent and reduce sexual and gendered harassment among younger adolescents are scarce. For schools, protecting pupils from harassment may be challenging if the behaviour is trivialised among the pupils themselves. In the current study, the school intervention "Stop Sexual Harassment" was therefore developed to help teachers and pupils detect, address and stop sexual and gendered harassment among pupils ages 13-15 in Norwegian secondary schools. Methods: In this study the effectiveness of "Stop Sexual Harassment" is evaluated via a cluster randomised controlled trial among pupils and teachers at 38 secondary schools. Schools were randomised into intervention and control groups. Primary outcomes are sexual and gendered harassment victimisation and perpetration, which will be assessed by the administration of questionnaires to pupils and teachers at baseline, and 2-, and 7-months follow-up. A process evaluation of the intervention implementation will be conducted through focus group interviews with pupils and teachers to gain insight about their experiences with the program components and implementation of the intervention. Discussion: If the intervention yields positive effects, large-scale implementation of the program may be offered for secondary schools. The program may thus reduce sexual and gendered harassment among young adolescents. Clinical trial registration: clinicaltrial.gov; identifier: NCT04716400.
