The translated scale was tested in two analytical samples with an age range of 50-95 years in 2020 (n = 548) and 2022 (n = 276). To assess reliabilities, internal consistencies and test-retest reliabilities are reported. To assess validity, we analyze the scale in the context of gender, age, and educational differences and its associations with measures of technology use and attitudes towards technology (convergent and divergent validity). The German adaptation of the MDPQ was found to be reliable and valid as the original version. The scale demonstrated an excellent internal consistency in both studies with α = 0.95 (study 2: α = 0.92) and ω = 0.95 (study 2: ω = 0.93). Subscale internal consistencies were all ≥ 0.65. Test-retest reliabilities with measurement waves 2 years apart showed excellent values (MDPQ full scale: r<sub>tt</sub> = 0.84, p < 0.001). We also found the expected factorial structure of the scale, positive associations with education, mobile device use and technology attitudes, and negative associations with age. Women scored lower than men. The German adaptation of the MDPQ can serve as a useful tool to estimate mobile device skills in older adults in German speaking countries in a reliable and valid way, for example in survey research, research projects, and practice contexts.

Also, research on family caregivers' role in enabling 'aging in place' for older relatives with migrant backgrounds is limited, despite many older non-European migrants' preference for family care in comparison to long-term institutional care. This study aims to explore the experiences and perspectives of family caregivers in the context of formal and informal care and their preferences regarding the place of care for older family members with migrant backgrounds, particularly the Pakistani Ahmadiyya community in Norway. Eighteen semi-structured individual interviews and two group interviews were conducted in Urdu and English with nineteen female family caregivers of older relatives, ages 25-62, residing in Norway. The analysis yielded three main themes: (1) \"Nursing homes are not for the ones who love their parents\", (2) Preferences for home with the possibility of sharing care, and (3) Mismatch between family care needs and formal care. Family caregivers' perception of health services has a decisive impact on their older relatives' demand and use of formal health services, emphasizing the need for trust.

The aim was to evaluate the cost-effectiveness of the Safe Step digital fall preventive exercise intervention over a period of 12 years and, in addition, to evaluate the impact of increased recruitment cost and decreased intervention effect. The intervention was evaluated in an observational study in a municipality context targeting community-dwelling older people of age 70 + . A Markov model with five states was used to model the cost-effectiveness of the Safe Step intervention and evaluate quality-adjusted life years (QALYs) and fall-related costs from a societal perspective. By using data from a meta-analysis as basis for the estimated intervention effect, the Safe Step intervention was compared with a no-intervention alternative. The results showed that the Safe Step intervention dominated no intervention. In the sensitivity analysis with the most conservative estimate of intervention effect, the ICER was €7 616 per QALY gained. Hence, Safe Step showed to be a cost-saving fall preventive intervention in older people at risk of falling and potentially cost-effective even with a low estimated intervention effect.
