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.

Background: Shared decision-making is a key element of person-centred care and promoted as the favoured model in preference-sensitive decision-making. Limitations to implementation have been observed, and barriers and limitations, both generally and in the palliative setting, have been highlighted. More knowledge about the process of shared decision-making in palliative cancer care would assist in addressing these limitations. Aim: To identify and synthesise qualitative data on how people with cancer, informal carers and healthcare professionals experience and perceive shared decision-making in palliative cancer care. Design: A systematic review and metasynthesis of qualitative studies. We analysed data using inductive thematic analysis. Data sources: We searched five electronic databases (MEDLINE, EMBASE, PsycINFO, CINAHL and Scopus) from inception until June 2023, supplemented by backward searches. Results: We identified and included 23 studies, reported in 26 papers. Our analysis produced four analytical themes; (1) Overwhelming situation of ‘no choice’, (2) Processes vary depending on the timings and nature of the decisions involved, (3) Patient-physician dyad is central to decision-making, with surrounding support and (4) Level of involvement depends on interactions between individuals and systems. Conclusion: Shared decision-making in palliative cancer care is a complex process of many decisions in a challenging, multifaceted and evolving situation where equipoise and choice are limited. Implications for practice: Implementing shared decision-making in clinical practice requires (1) clarifying conceptual confusion, (2) including members of the interprofessional team in the shared decision-making process and (3) adapting the approach to the ambiguous, existential situations which arise in palliative cancer care.

Muscular strength is associated with functional ability in elderly, and older adults are recommended to perform muscle-strengthening exercise. Understanding how improved muscle strength and -mass influence general and specific domains of quality of life is important when planning health promotion efforts targeting older adults. The aims of the present study were to describe changes in health-related quality of life (HRQOL) in older men participating in 12 weeks of systematic strength training, and to investigate whether improvements in muscle strength and muscle mass are associated with enhancements in HRQOL. We recruited 49 men aged 60–81 years to participate in an intervention study with pre-post assessment. The participants completed a 12-week strength training program consisting of three sessions per week. Tests and measurements aimed at assessing change in HRQOL, and changes in physical performance (maximal strength) and physiological characteristics. HRQOL was measured using the 12-item short-form survey (SF-12). Muscle mass was assessed based on changes in lean mass (leg, trunk, arm, and total), and strength was measured as one-repetition maximum in leg extension, leg press, and biceps curl. Two of the eight HRQOL SF-12 scores, role physical and general health, and the physical component summary scores, increased significantly during the intervention period. Small significant positive correlations were identified between improvements in muscle strength, and better physical and social function. Moreover, a significant increase in total muscle mass was seen during the intervention period. The positive, findings from this study would suggest that systematic strength training seems to be a beneficial intervention to improve HRQOL, muscle strength and muscle mass in older men.

Background: For many adults, their role as a parent is a vital part of their lives. This role is likely to be associated with a parent’s health-related quality of life (HRQOL). The aim of this study was to explore the associations between gender, demographic and psychosocial variables, pain, and HRQOL in parents of 14–15-year-old adolescents. Methods: This was a cross-sectional study that included 561 parents. Data on demographic, psychosocial variables and pain were collected using validated instruments. HRQOL was assessed using the RAND-36. Data were analysed using univariate and hierarchical multiple linear regression analyses. Results: Four hundred and thirty-six (78%) mothers and 125 (22%) fathers with a mean age of 45 (SD = 5) years were included. Eighty-one per cent were married/cohabiting, 74% worked full time, and 50% had university education of more than 4 years. Almost one-third reported daily or weekly pain, and more than half (58%) reported using pain analgesics during the previous 4 weeks. Mothers reported significantly lower scores on self-efficacy, self-esteem and for all RAND-36 domains, including the physical component summary (PCS) and mental component summary (MCS) and experienced greater stress than fathers. Hierarchical regression analyses showed that working part-time (beta = 0.40) or full time (beta = 0.52) (reference: not working) had the strongest positive effect on PCS. Absence from work for > 10 days (beta = −0.24) (reference: no absence), short-term pain (beta = −0.14), chronic pain (beta = −0.37) (reference: no pain), and stress (beta = −0.10) had the strongest negative effects on PCS. High self-esteem (beta = 0.11) had the strongest positive effect, whereas stress (beta = −0.58) and absence from work for > 10 days (beta = −0.11) (reference: no absence) had the strongest negative effects on MCS. Conclusion: Mothers reported significantly lower scores on self-efficacy, self-esteem, and HRQOL, and experienced greater stress than the fathers. A high proportion of parents reported pain. Pain, stress, and low work affiliation were strongly associated with decreased HRQOL in parents. We recommend that parents of adolescents should be provided guidance about coping with pain and stress, and facilitation of a strong work affiliation because these seem to be important to parents’ HRQOL.

The long-term effect of hip fracture on health-related quality of life (HRQOL) and global quality of life (GQOL) has not been thoroughly studied in prospective case-control studies.

Two models were developed to increase high school students’ participation in physical education (PE): “motion enjoyment” and “sport enjoyment”. The first model focuses on increasing knowledge about the health benefits of a physically active lifestyle and thereby promoting a positive attitude towards physical activity, whereas the second model focuses on techniques and practices for enhancing athletic performance. The aims of the present study are to investigate and understand the similarities and differences between students selecting “motion enjoyment” vs. “sport enjoyment” and to examine the extent to which life goals and reported physical activity are associated with health-related quality of life (HRQOL). A total of 156 high school students (mean age, 16 years [standard deviation = 0.8], 123 girls and 33 boys) were included in this cross-sectional study. HRQOL and life goals were measured using KIDSCREEN-10 and the Adolescent Life Goal Profile Scale, respectively. Physical activity was measured using a self-reporting questionnaire intended to describe the students’ leisure-time activity. Independent sample t-tests, chi-square, one-way analyses of variance and multiple regression analysis were applied. Self-reported physical activity level and HRQOL were higher among students in the “sport enjoyment” program, while the perceived importance of life goals was the same regardless of the preferred PE model. Multiple regression analyses revealed that the perceived importance of relations-oriented life goals (B = −5.61; 95 % confidence interval CI = −10.53 to −0.70; p = .026), perceived importance of generativity-oriented life goals (B = 4.14.; 95 % CI = 0.85 to 7.422; p = .014), perceived attainability of relations-oriented life goals (B = 7.28; 95 % CI = 2.49 to 12.07; p = .003), age (B = −7.29; 95 % CI = −11.38 to −3.20; p = .001) and gender, with boys as the reference group (B = −12.10; 95 % CI = −19.09 to −5.11; p = .001), were independently associated with increased HRQOL. In exploring the relationships of self-reported physical activity during leisure time, stage of change (B = 3.53; 95 % CI = 1.49 to 5.51; p = .001), gender, with boys as the reference group (B = −8.90; 95 % CI = −15.80 to −2.00; p = .012), and age (B = −6.62; 95 % CI = −10.57 to −2.66; p = .001) were independently associated with increased HRQOL. Self-reported physical activity habits and life goals were associated with HRQOL to a limited extent. However, the perceived importance of life goals appears to reflect other aspects of individual well-being than HRQOL.
