A systematic review of quality of life research in medicine and health sciences
Purpose Quality of life (QOL) is an important concept in the field of health and medicine. QOL is a complex concept that is interpreted and defined differently within and between disciplines, including the fields of health and medicine. The aims of this study were to systematically review the literature on QOL in medicine and health research and to describe the country of origin, target groups, instruments, design, and conceptual issues. Methods A systematic review was conducted to identify research studies on QOL and health-related quality of life (HRQOL). The databases Scopus, which includes Embase and MEDLINE, CINAHL, and PsycINFO were searched for articles published during one random week in November 2016. The ten predefined criteria of Gill and Feinstein were used to evaluate the conceptual and methodological rigor. Results QOL research is international and involves a variety of target groups, research designs, and QOL measures. According to the criteria of Gill and Feinstein, the results show that only 13% provided a definition of QOL, 6% distinguished QOL from HRQOL. The most frequently fulfilled criteria were: (i) stating the domains of QOL to be measured; (ii) giving a reason for choosing the instruments used; and (iii) aggregating the results from multiple items. Conclusion QOL is an important endpoint in medical and health research, and QOL research involves a variety of patient groups and different research designs. Based on the current evaluation of the methodological and conceptual clarity of QOL research, we conclude that the majority QOL studies in health and medicine have conceptual and methodological challenges.

Psychometric Properties of the Slovak Version of sEMBU on General Adult Sample
The factorial stability and reliability of the 23-item s(short)- EMBU previously demonstrated to be satisfactory in the samples of students from Greece, Guatemala, Hungary, Italy (1999), East-Germany and Sweden (Arrindell et al., 2001). The Slovak translation of the original sEMBU was published in 2007 (Poliaková, Mojžišová, & Hašto, 2007). We decided to explore the psychometric properties of the translation of sEMBU on a general adult sample (N=970) in Slovakia, because the translated version of sEMBU is already utilized in research projects in Slovakia. The results show a very good alpha reliability of sEMBU. In the Slovak translation, we found similar scores of Rejection and Emotional warmth and Overprotection. A factor analysis with forced 3-factor solution sorted items to scales exactly as authors of sEMBU presupposed. Overprotection (father) has the highest share for classification and differentiation in the cluster. Emotional warmth (mother) has the highest share for classification and differentiation in the cluster. We discussed our results with the results from other studies and we suggest to continue in the research of the Slovak version of sEMBU focused on types of attachment, especially on the secure type of attachment.

Predictors of rate of change for children and youth with emotional disorders: a naturalistic observational study
To examine demographic and clinical characteristics as potential predictors of change for children and youth with emotional disorders treated at two child and adolescent mental health outpatient services (CAMHS) in Norway. The study was of naturalistic observational type with “treatment as usual” (TAU). The sample consisted of 84 children and youth with emotional disorders. The Health of the Nation Outcome Scale (HONOSCA), and the Children’s Global Assessment Scale (CGAS) were administered at intake (T0), during the assessment (T1) and approximately six months after assessment (T2). Change was analysed by means of the linear mixed models procedure. For the HONOSCA total score, youths with a diagnosis of depression had statistically higher symptom severity levels at baseline and significantly lower change rates as compared to youths with an anxiety disorder. The current study adds to the limited knowledge of predictors of rate of change for children and adolescents with emotional disorders treated within CAMHS. Our results point to a special need to improve clinical care for depressed children and adolescents. Important limitations comprising the external validity of the study concern missing data, a small study sample, and lack of information regarding the content and extent of the service provided.

Brief Report: Parent-Reported Problems Related to Communication, Behavior and Interests in Children with Autistic Disorder and Their Impact on Quality of Life
Parents of children with Autism spectrum disorders often report elevated levels of stress, depression and anxiety compared to parents of children with other developmental disorders. The present study investigated experiences of mothers of children with autistic disorder, both boys and girls. The results show that mothers report problems related to communication, behavior and interests of their child, which impact their quality of life. There were also differences between boys and girls.

Preventing alcohol use with a universal school-based intervention: results from an effectiveness study
The effectiveness of the universal school-based alcohol prevention program “Unge & Rus” [Youth & Alcohol] was tested by an independent research group. The program aims to prevent alcohol use and to change adolescents’ alcohol-related attitudes. The main outcome measure was frequency of monthly alcohol use, favorable alcohol attitudes, perceived behavioral control (PBC), positive alcohol expectancy and alcohol-related knowledge. Junior high school students (N = 2,020) with a mean age of 13.5 years participated in this longitudinal pre, post and one-year follow-up study with a quasi-experimental design, involving an intervention group and a comparison group recruited from 41 junior high schools in Norway. Multilevel analysis was used to account for the repeated observations (level 1) nested within students (level 2) who in turn were clustered within school classes (level 3). Results showed an increased level of alcohol-related knowledge in the intervention group (p < .005) as compared to the comparison group at one-year follow-up. However, no significant difference in change was found between the intervention group and the comparison group in frequency of monthly alcohol use, alcohol-related attitudes, PBC or alcohol expectancy at one-year follow-up. This study offers adequate data on the effectiveness of a school-based alcohol prevention program widely implemented in Norway. Under its current method of implementation, use of the program cannot be supported over the use of standard alcohol curriculum within schools.

Uptake and adherence of a self-directed internet-based mental health intervention with tailored e-mail reminders in senior high schools in Norway
Internet-based cognitive behavioural therapy (ICBT) is a promising approach to the prevention and reduction of depressive symptoms among adolescents. This study aimed to evaluate the feasibility and efficacy of disseminating a self-directed internet-based mental health intervention (MoodGYM) in senior high schools. It also sought to investigate possible effects of tailored and weekly e-mail reminders on initial uptake and adherence to the intervention. A baseline survey was conducted in four senior high schools in two Norwegian municipalities (n = 1337). 52.8% (707/1337) of the students consented to further participation in the trial and were randomly allocated to one of three MoodGYM intervention groups (tailored weekly e-mail reminder (n = 175), standardized weekly e-mail reminder (n = 176 ) or no e-mail reminder (n = 175)) or a waitlist control group (n = 180). We tested for effects of the intervention on depression and self-esteem using multivariate analysis of variance, effects of tailored e-mail and self-reported current need of help on initial uptake of the intervention using logistic regression and the effect of weekly e-mails on adherence using ordinal regression. There was substantial non-participation from the intervention, with only 8.5% (45/527) participants logging on to MoodGYM, and few proceeding beyond the first part of the programme. No significant effect on depression or self-esteem was found among the sample as a whole or among participants with elevated depression scores at baseline. Having a higher average grade in senior high school predicted initial uptake of the intervention, but tailored e-mail and self-reported current need of help did not. Weekly e-mail prompts did not predict adherence. The main reasons for non-use reported were lack of time/forgetting about it and doubt about the usefulness of the program. Overall, disseminating a self-directed internet-based intervention to a school population proved difficult despite steps taken to reduce barriers in terms of tailoring feedback and dispatching weekly e-mail reminders. Providing mental health interventions within the school environment is likely to ensure better uptake among senior high school students, but there is a need to effectively communicate that such programmes can be helpful. The trial was registered retrospectively as ACTRN12612001106820

Motivation to persist with internet-based cognitive behavioural treatment using blended care: a qualitative study
The prevalence of depression is high and results in huge costs for society. Internet-based cognitive behavioural treatment (ICBT) has been suggested for use in primary care and has been shown to be more effective when combined with human support. However, non-completion rates remain a challenge. Current recommendations state that steps to improve persistence with ICBT should be determined and the impact of therapist support on persistence explored. A few earlier studies have explored motivations to persist with ICBT without face-to-face therapist support. The present study explored the motivation to persist as experienced by a group of patients who sought help in primary care and used “blended care”, i.e. ICBT supported by short face-to-face consultations. To elucidate motivation in an everyday context and the meaning of patients’ experiences we chose a phenomenological hermeneutical approach. We interviewed participants in the intervention group of a randomized controlled trial that evaluated the efficacy of an ICBT programme called MoodGYM, an eHealth intervention used to treat depression. Fourteen participants, both completers and non-completers, went through individual, semi-structured interviews after they ended their treatment. Hope of recovery and a desire to gain control of one’s life were identified as intrinsic motivators. The feeling of being able to freely choose how, when and where to complete the ICBT modules was identified as an important supporting condition and satisfied the participants’ need for autonomy. Furthermore, the importance of a sense of belonging towards partners, friends or family was essential for motivation as was the ability to identify with ICBT content. Another supporting condition was the experience of connectedness when met with acknowledgement, flexibility and feedback from a qualified therapist in the face-to-face consultations. A key finding was that participants were motivated to persist with ICBT when their overall need for relatedness was satisfied. This was achieved through a sense of belonging towards partners, friends and family. Connectedness with the therapist and the participant’s ability to identify with the ICBT modules also gave a sense of relatedness. Improving these motivational aspects may increase patients’ persistence with ICBT.

Invisible emotional expressions influence social judgments and pupillary responses of both depressed and non-depressed individuals
We used filtered low spatial frequency images of facial emotional expressions (angry, fearful, happy, sad, or neutral faces) that were blended with a high-frequency image of the same face but with a neutral facial expression, so as to obtain a “hybrid” face image that “masked” the subjective perception of its emotional expression. Participants were categorized in three groups of participants: healthy control participants (N = 49), recovered previously depressed (N = 79), and currently depressed individuals (N = 36), All participants were asked to rate how friendly the person in the picture looked. Simultaneously we recorded, by use of an infrared eye-tracker, their pupillary responses. We expected that depressed individuals (either currently or previously depressed) would show a negative bias and therefore rate the negative emotional faces, albeit the emotions being invisible, as more negative (i.e., less friendly) than the healthy controls would. Similarly, we expected that depressed individuals would overreact to the negative emotions and that this would result in greater dilations of the pupil's diameter than those shown by controls for the same emotions. Although we observed the expected pattern of effects of the hidden emotions on both ratings and pupillary changes, both responses did not differ significantly among the three groups of participants. The implications of this finding are discussed.

Oral health-related quality of life among 12-year-olds in Northern Norway and North-West Russia.
To assess self-perceived oral health-related quality of life (OHRQoL) in 12-year-olds living in two areas in the Barents region: North-West Russia (Arkhangelsk) and Northern Norway (Tromsø). Sampling was performed according to a stratified cluster design and consisted of 590 Russian and 264 Norwegian 12-year-olds and their parents. After written consent from their parents, 514 Russian (87% attendance) and 124 Norwegian (47% attendance) children entered the study. The study included clinical examination (children) and questionnaires (children and parents). Dental caries and the aesthetic dental appearance were recorded under field conditions. Self-reports on background variables and oral health-related quality of life questions (CPQ11-14) were completed in classroom settings by children and at home by parents. OHRQoL was found to vary depending on country of origin, with higher scores of CPQ11-14 domains among 12-year-olds from Russia. OHRQoL was found to be associated with dental caries, with higher scores among 12-year olds with caries. Inferior emotional and social well-being were established as having the strongest association with quality of life. Dental caries showed an independent effect on OHRQoL scores, but this effect disappeared when controlling for background variables, with country of origin, family economy, parental education and aesthetic appearance as the most influential (R²=0.14). Norwegian 12-year-olds had better oral health and OHRQoL than their Russian counterparts. The impact of dental caries on OHRQoL was weak and aesthetic dental appearance and socio-economic determinants were found to be more important, probably reflecting the great differences in the standards of living between Northern Norway and North-West Russia.
