Effectiveness of Psychotherapy for Community-Dwelling Vulnerable Older Adults with Depression and Care Needs: Findings from the PSY-CARE Trial.

BACKGROUND: For older adults with care needs, evidence for the effectiveness of psychotherapy on depression is scarce. METHODS: In PSY-CARE, a pragmatic randomized controlled trial, N = 197 home-living older adults with depression and care needs were randomized into outpatient psychotherapy or an active control condition. Residential psychotherapists offered age-sensitive cognitive-behavioral psychotherapy (at-home if needed). Control group participants received telephone counseling and a self-help guide. Outcomes were assessed at baseline (T1), after (T2), 3 months after (T3), and 12 months after the intervention (T4). RESULTS: There was a significant decrease in depressive symptoms across both arms with Cohen's d T4-T1 = .52 in the psychotherapy and .55 in the control group. Mixed models revealed no statistically significant difference in primary and secondary outcomes between interventions. Posthoc, we found control group participants with greater ADL limitations experienced significantly increased depressive symptoms compared to those reporting lower limitations. CONCLUSIONS: Interventions were successful in reducing depressive symptoms, even though treatment fidelity was decreased due to the COVID-19 pandemic. We could not demonstrate superior effectiveness of psychotherapy for older adults with care needs. CLINICAL IMPLICATIONS: Findings suggest that psychotherapy may be an important and superior treatment to circumvent aggravation of depression in older patients with high functional limitations. TRIAL REGISTRATION: The trial was prospectively registered with the ISRCTN registry (Trial registration number: ISRCTN55646265, February 15, 2019).

'Who tells me when to stay active or to leave?' age differences in and predictors of endorsement of prescriptive views of aging.

OBJECTIVES: Prescriptive views of aging (PVoA) are normative age-based expectations about age-appropriate behavior for older adults, e.g. that they should stay fit/active (active aging norms) but also behave altruistically toward younger generations (altruistic disengagement norms). We aimed at examining age differences in endorsement of active aging and altruistic disengagement and investigated predictors of endorsement. METHOD: In the AGEISM Germany survey, a representative sample of N = 1,915 German participants was recruited, covering a wide age range (Mage=56.57 years, 16-96 years). Cross-sectional data was collected via computer-assisted telephone interviews. RESULTS: Active aging was more strongly endorsed than altruistic disengagement. Endorsement of both PVoA was higher in older age groups - even more pronounced for altruistic disengagement. Endorsement of both norms was positively associated with positive age stereotypes. Furthermore, active aging was predicted by age centrality whereas altruistic disengagement was predicted by negative age stereotypes. Age was still a robust predictor of PVoA even after entering additional predictors. CONCLUSION: Although associated, prescriptive age norms (i.e. beliefs how older people should behave) and descriptive age norms (i.e. beliefs about how older adults and the aging process are like) represent partly independent belief systems, highlighting the importance to assess & further investigate predictors and consequences of PVoA, which become more prevalent with age.

[Strengthening prevention and health promotion in and for old age]. / Prävention und Gesundheitsförderung im und für das Alter stärken.

BACKGROUND: Disease prevention and health promotion in and for old age have become increasingly more important. Nevertheless, more (national) research and implementation in practice is needed, as the international comparison shows. OBJECTIVE: To develop guiding principles for research and practice on prevention and health promotion in and for old age. MATERIAL AND METHODS: As part of an iterative process, members of the German Society of Gerontology and Geriatrics came together in workshops and symposia to formulate key guiding principles and fields of action for prevention and health promotion. RESULTS: The following were worked out: 1) prevention and health promotion are useful and possible up to oldest age, 2) prevention and health promotion for advanced age should start early, 3) prevention and health promotion must take into account the diversity and heterogeneity of the life situations of old people, 4) prevention and health promotion promote and demand self-determination and participation, 5) prevention of multiple illnesses must be given greater attention, 6) prevention of the need for long-term care and prevention in long-term care must be treated equally, 7) prevention and health promotion must be thought of in terms of life worlds and across sectors, paying particular attention to aspects of social inequality and a focus on resources, 8) prevention and health promotion and the related research must be interdisciplinary and transdisciplinary and be applied at different levels, from molecular to societal. DISCUSSION: The guiding principles outline the focal points of future-oriented ageing, health and healthcare research and open up fields of action but also show the limits of this approach for political decision-makers, researchers and practitioners.

Psychotherapists' experiences providing at-home psychotherapy for home-living older adults with long-term care needs and depression.

This study used qualitative methods to explore psychotherapists' experiences conducting at-home psychotherapy with older adults (60 + years) with long-term care needs and depression. We conducted semistructured interviews with 16 female psychotherapists (26-70 years old) who delivered at-home cognitive behavioral therapy to home-living older adults with long-term care needs and depression. We additionally conducted 10 patient case studies. Using an adaption of the methodology of grounded theory, we iteratively developed a hierarchical model. Results showed that psychotherapists experienced three dilemmas: (a) pushing for change versus acknowledging limitations, (b) providing help versus maintaining boundaries, and (c) being a guest in the patient's home versus the host of a psychotherapy session. The absence of a shared understanding of therapy and confrontation with patients' existential suffering intensified the experience of the dilemmas. The dilemmas generated professional self-doubt and negative emotions, which in turn triggered a reflexive process and ultimately participants' professional development. Participants found a way to integrate drives initially perceived as mutually exclusive, and further developed their professional self-image and therapeutic techniques. We interpret the dilemmas as reflecting difficulty reconciling the "curing" and "caring" treatment paradigms. Practice and support managing the three dilemmas along with reflection on the curing paradigm, views on old age, and fear of existential suffering should be part of qualifications for psychotherapists working with older adults in need of care. Cooperating with other care providers may relieve the pressure on psychotherapists to provide forms of support that could lead to overburden and impede therapeutic progress.

Life-space mobility among home-living older adults with care needs and clinical depression-A cross-sectional analysis.

OBJECTIVES: While life-space mobility is key for wellbeing, social participation and access to health care, vulnerable older adults face physical and mental barriers that may restrict mobility. The present exploratory study examined associations between physical functional limitations, depressive symptoms, life-space mobility and outpatient health care utilization. METHODS: Cross-sectional data from 197 community-dwelling older adults with care needs and clinical depression was collected. Life-space assessment composite score (LS-C), instrumental activities of daily living scale (iADL), Geriatric Depression Scale (GDS-12) and outpatient health care utilization have been assessed. Multiple regression analyses were conducted. RESULTS: Mean LS-C score was 31.8 (SD = 17.7, range: 0-92), indicating low mobility levels. Depressive symptoms (ß = -0.21, p = 0.001) and iADL (ß = 0.54, p < 0.001) were significantly related with life-space mobility, over and above age and living alone. An interaction effect between depressive symptoms and iADL was not significant (ß = -0.07, 0.17, p = 0.26). Moreover, life-space mobility was positively associated with primary care (ß = 0.19, p = 0.02) and mental health care utilization (ß = 0.33, p < 0.001). CONCLUSIONS: Life-space mobility appears to be largely restricted in home-living vulnerable older adults with clinically significant depression; and factors associated with these restrictions appear to be physical and mental. The interplay of depression, mobility and health care utilization and its potential for interventional approaches need further investigations. Present findings underline an urgent need for new health care services that allow mobility-impaired older patients to receive mental health outpatient treatment in their own home. CLINICAL TRIAL REGISTRATION: The trial was prospectively registered with the ISRCTN registry (Trial registration number: ISRCTN55646265, registered February 15, 2019).

Experiences of Home-living Vulnerable Older Adults with Clinical Depression during the COVID-19 Pandemic: A Qualitative Study.

OBJECTIVES: Little is known about the diversity of older adults' experiences during the COVID-19 pandemic. We therefore investigated the pandemic experiences of home-living vulnerable older adults with depression, an understudied subpopulation. METHODS: We conducted unstructured interviews with N= 20 older (60+ years) adults with clinical depression receiving care in their homes in June and again in December 2020. Interviews were coded according to the grounded theory approach. RESULTS: We identified eight themes. Participants described feeling disconnected before and during the pandemic, which they attributed to their physical impairments and old age. Their social relations with family, medical providers, and caregivers helped them feel connected. Participants did not feel significantly impacted by the COVID-19 pandemic, but they missed social and physical contact. During the pandemic, isolation was normalized. Participants therefore experienced loneliness due to their isolation, but also a sense of togetherness with the rest of society. Isolation within the home was re-framed as cocooning, which provided a sense of autonomy. Participants nevertheless expressed resignation. CONCLUSIONS: Home-living vulnerable older adults with depression experienced loneliness but also a degree of relief during the pandemic. CLINICAL IMPLICATIONS: Positively re-framing isolation and the stability of formal caregiving helped participants endure feeling disconnected during the pandemic.

[Feasibility, Practicability, and Acceptance of Outpatient Psychotherapy for Home-living Older Adults with Depression in Need of Care in Germany]. / Implementierbarkeit, Praktikabilität und Akzeptanz ambulanter Psychotherapie für zuhause lebende ältere Menschen mit Depression und Pflegebedarf ­ Ergebnisse des Innovationsfondsprojekts PSY-CARE.

OBJECTIVE: This study investigates the feasibility of outpatient psychotherapeutic depression-treatment for home living older adults in need of care within the German health-care system. METHODS: PSY-CARE is a manual based, pragmatic randomized controlled trial investigating the effects of short-term behavioural therapy for home living adults aged 60+ with clinical depression and need of care. RESULTS AND CONCLUSION: Our results suggest that health policy should implement home-visits, interprofessional cooperation and involvement of relatives as standard outpatient psychotherapy elements. Specialised geropsychological training for psychotherapists is needed.

(In)visible and (Un)heard? Older Adults as Guests on COVID-Related Political Talk Shows in Germany.

Background and Objectives: The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected older adults. Despite calls to include older people in societal decision making, the extent to which older adults have participated in the pandemic-related public debate is unknown. This study investigated older adults' (65+ years) voice and visibility as guests on political talk shows as an important arena of public debate. Specifically, we examined how often older adults appeared as guests, their characteristics, and how older versus younger guests discussed the pandemic. Research Design and Methods: Judges assessed all guests' age, gender, migration experience, functional aids, and professional background on all episodes of the 4 most-watched political talk shows in Germany between January 1 to December 31, 2020 (N = 136 episodes, K = 754 guests). We used an exploratory sequential mixed-methods approach and frame analysis on all episodes featuring older guests (n = 37), to first identify how guests discussed the pandemic, and then assess differences in positions between older and younger guests (<65 years). Results: Older guests rarely appeared (12.2% of all guests, 9.6% of guests on COVID-related episodes) and if they did, they were majorly male, young-old, German-born professionals with no functional aids. Rather than appearing as "peer advocates" of older adults, older guests framed the pandemic similarly to younger guests, with a tendency to more strongly address disproportionate restrictions of civil liberties in society. Discussion and Implications: Results suggest that one prominent part of German media failed to represent the diverse voice of a population most affected by the COVID-19 pandemic in 2020. Differences between how older and younger guests discussed the pandemic may reflect their privileged background in addition to generational differences in attitudes toward government. Future research in other social fora and of other social groups of older adults might facilitate understanding how older adults shaped the public debate on the COVID-19 pandemic.

Responding to Covid-19: an analysis of position statements of gerontological societies worldwide.

The Covid-19 pandemic, with its adverse implications for older adults, has generated unprecedented public interest in issues around age and ageing globally. We systematically investigated the responses of national gerontological and geriatric societies (NGGS) to emerging challenges during the first wave of the pandemic. Framed within traditional research topics in gerontology, the aim was to identify the spectrum of focal points and positions directed towards governments, policy makers, researchers and society. A comprehensive, two-phased data collection strategy generated N = 22 position statements of NGGS affiliated to the International Association of Gerontology and Geriatrics. Using Ayalon et al. (J Gerontol Ser B, 2020. 10.1093/geronb/gbaa066) thematic categorisation of gerontological research, we applied quantitative and qualitative content analysis to analyse "calls for action" within the statements. The content of NGGS' position statements show a high level of agreement on the salient topics during the first wave of the pandemic and reveal shared values such as equality, diversity and inclusion of older adults and the discipline of gerontology to be an applied one with relevance to policy and practice. The results can support future interdisciplinary research in gerontology post Covid-19 based on a vision to contribute to a society of all ages.

Concordance of self- and informant-rated depressive symptoms in nursing home residents with Dementia: cross-sectional findings.

BACKGROUND: Depression is highly prevalent in nursing home residents living with moderate to severe dementia. However, assessing depressive symptoms in residents with dementia can be challenging and may vary by rater perspective. We aimed to investigate the concordance of, and factors associated with self- and informant-rated depressive symptoms in nursing home residents with dementia. METHODS: Cross-sectional data was collected from N = 162 nursing home residents with dementia (age: 53-100; 74% women). Self-ratings were assessed with the Geriatric Depression Scale, while the depression and anxiety items of the Neuropsychiatric Inventory were used for informant-ratings. Cohen's Kappa was calculated to determine the concordance of both measures and of each with antidepressant medication. Multivariate associations with sociodemographic variables, self- and informant-rated quality of life, dementia stage, neuropsychiatric symptoms, functional status and antidepressant medication were analysed with linear mixed models and generalized estimating equations. RESULTS: Concordance between self- and single item informant-rated depressive symptoms was minimal (Cohen's Kappa = .22, p = .02). No concordance was found for self-reported depressive symptoms and the combined informant-rated depression-anxiety score. Self-reported depression was negatively associated with self-rated quality of life (ß = -.32; 95%CI: -.45 to -.19, p < .001), informant-rated quality of life (ß = -.25; 95%CI: -.43 to -.07, p = .005) and functional status (ß = -.16; 95%CI: -.32 to -.01, p = .04), whilst single item informant-rated depression revealed negative associations with informant-rated quality of life (ß = -.32; 95%CI: -.52 to -.13, p = .001) and dementia stage (ß = -.31; 95%CI: -.52 to -.10, p = .004). The combined informant-rated depression-anxiety score showed negative associations with self-rated quality of life (ß = -.12; 95%CI: -.22 to -.03, p = .01) and dementia stage (ß = -.37; 95%CI: -.67 to -.07, p = .02) and a positive association with neuropsychiatric symptoms (ß = .30; 95%CI: .10 to .51, p = .004). No concordance was found with antidepressant medication. CONCLUSIONS: In line with our expectations, low agreement and unique association patterns were found for both measures. These findings indicate that both instruments address different aspects of depression und underline the need for comprehensive approaches when it comes to detecting signs of clinically relevant depressive symptoms in dementia. TRIAL REGISTRATION: The trial was registered with the ISRCTN registry (Trial registration number: ISRCTN98947160 ).

Evaluation of Recruitment Strategies for Home-Living Vulnerable Older Adults With Depression: Findings From a Randomized Controlled Psychotherapy Trial.

OBJECTIVE: Vulnerable older adults, such as physically impaired or care-dependent individuals, are vastly underrepresented in psychotherapy research. Improving their inclusion in randomized controlled trials is necessary to determine the effectiveness of psychotherapy in this population. This study is the first to systematically evaluate strategies to recruit home-living vulnerable older adults with clinically significant depression into a large randomized controlled psychotherapy trial. Potential participants were approached directly (self-referral) or via cooperation with gatekeepers (gatekeeper-referral). METHODS: Successful recruitment strategies and the person initiating the first contact with the study team were recorded. Recruitment strategies were compared with respect to the number of inquiries and inclusion rates, study personnel's time investment, and participant characteristics (sociodemographics, functional and cognitive status, depression and anxiety scores). RESULTS: Most of the N = 197 participants were included via gatekeeper-referral (80.5%, 95% confidence interval = [74.9, 86.1]), but time investment for gatekeeper-referrals was five times higher than for self-referral by media reports. Clinical psychologists and medical practitioners referred the largest proportion of participants (32.3% each) and referral by medical practitioners led to highest inclusion rates (55.6%; χ²(3) = 8.964, p <0.05). Most participants were referred from a hospital setting (50.3%), whereas referral numbers by medical practices were low (15.9%). Participants who initiated the first contact themselves had higher inclusion rates and were less functionally impaired. CONCLUSION: Including home-living vulnerable older adults into psychotherapy trials requires simultaneous implementation of diverse recruitment strategies. Medical practitioners and psychologists, especially in hospitals, are the most effective recruitment strategy, but self-referral via media is most cost-efficient in terms of time investment.

How young psychotherapists experience working with older patients.

Preliminarily findings from experimental and survey research suggests that psychotherapy with older adults is an area of practice in which psychotherapists do not feel positive and confident. This qualitative study is the first to explore how young psychotherapists experience and perceive their therapeutic work with older patients. To do so, we provide an in-depth perspective of how young (aged 27-35) psychotherapists experience providing psychotherapeutic treatment for older patients (aged over 65). Semistructured interviews were conducted with 20 psychotherapists in training (14 women, six men). They were recruited via psychotherapeutic training institutions and geropsychiatry clinics in Germany. The grounded theory approach was used to analyze the data. We found that the participants had various attitudes toward older adults (respectful/admiring, caring/supportive, doubtful, and open) that were related to individual social and biographic experiences with older adults. The participants' attitudes and personal experiences were also found again in their reported therapeutic behavior toward older patients. The finding further showed that the treatment setting (inpatient vs. outpatient) had an additional impact on the participants' perception of and therapeutic behavior toward older patients. Our findings demonstrated that the participants experienced various challenges and particularities when working with older patients. Young psychotherapists who work with older patients should be supported by psychotherapeutic training institutions through supervision and guidance on how to deal with clinical challenges. Furthermore, it can be valuable for young psychotherapists to critically reflect their attitudes toward older adults and personal motives for their therapeutic behavior toward older patients.

Mn12 -Acetate Complexes Studied as Single Molecules.

The phenomenon of single molecule magnet (SMM) behavior of mixed valent Mn12 coordination clusters of general formula [MnIII 8 MnIV 4 O12 (RCOO)16 (H2 O)4 ] had been exemplified by bulk samples of the archetypal [MnIII 8 MnIV 4 O12 (CH3 COO)16 (H2 O)4 ] (4) molecule, and the molecular origin of the observed magnetic behavior has found support from extensive studies on the Mn12 system within crystalline material or on molecules attached to a variety of surfaces. Here we report the magnetic signature of the isolated cationic species [Mn12 O12 (CH3 COO)15 (CH3 CN)]+ (1) by gas phase X-ray Magnetic Circular Dichroism (XMCD) spectroscopy, and we find it closely resembling that of the corresponding bulk samples. Furthermore, we report broken symmetry DFT calculations of spin densities and single ion tensors of the isolated, optimized complexes [Mn12 O12 (CH3 COO)15 (CH3 CN)]+ (1), [Mn12 O12 (CH3 COO)16 ] (2), [Mn12 O12 (CH3 COO)16 (H2 O)4 ] (3), and the complex in bulk geometry [MnIII 8 MnIV 4 O12 (CH3 COO)16 (H2 O)4 ] (5). The found magnetic fingerprints - experiment and theory alike - are of a remarkable robustness: The MnIV 4 core bears almost no magnetic anisotropy while the surrounding MnIII 8 ring is highly anisotropic. These signatures are truly intrinsic properties of the Mn12 core scaffold within all of these complexes and largely void of the environment. This likely holds irrespective of bulk packing effects.

Does age matter? Initial treatment goals of older adults with major depression in outpatient cognitive behavioural therapy.

BACKGROUND: Personal treatment goals (PTG) are important means to tailor psychotherapy to the needs of the patient, leading to increased engagement and greater improvement in relevant outcomes. According to lifespan developmental research, motivational goals in old age differ from goals of younger people, with management of losses rather than growth becoming more prevalent. However, this study is the first to systematically investigate age-specific differences in PTGs. METHOD: We used routine data from patients with major depression assessed at the beginning of outpatient cognitive behavioural therapy. Initial high-priority PTGs were assessed using the Bern Inventory of Treatment Goals (BIT-C). Older patients (≥60 years, n = 52) were matched to younger patients (<60 years, n = 52) with regard to severity of depression, number of comorbidities, gender and level of education. RESULTS: Using a mixed method approach, high-priority PTGs of both age groups were focused most strongly on reducing depressive symptoms and, subsequently, anxiety. At the same time, older patients focused more strongly on PTGs related to well-being and functioning, while younger patients' emphasis was on personal growth. Furthermore, better coping with the ageing process and physical losses emerged as important PTGs for some older patients. CONCLUSION: Initial PTG themes are specific to diagnosis, but also seem to differ in regard to age. Thus, it is important to develop age-sensitive measures that allow appropriate and efficient tailoring of psychotherapy to meet older patients' needs and preferences.

Perceived need for treatment and non-utilization of outpatient psychotherapy in old age: two cohorts of a nationwide survey.

BEACKGROUND: Older adults with mental health problems may benefit from psychotherapy; however, their perceived need for treatment in relation to rates of non-utilization of outpatient psychotherapy as well as the predisposing, enabling, and need factors proposed by Andersen's Model of Health Care Utilization that account for these differences warrant further investigation. METHODS: We used two separate cohorts (2014 and 2019) of a weighted nationwide telephone survey in Germany of German-speaking adults with N = 12,197 participants. Across the two cohorts, 12.9% (weighted) reported a perceived need for treatment for mental health problems and were selected for further analyses. Logistic Generalized Estimation Equations (GEE) was applied to model the associations between disposing (age, gender, single habiting, rural residency, general health status), enabling (education, general practitioner visit) non-utilization of psychotherapy (outcome) across cohorts in those with a need for treatment (need factor). RESULTS: In 2014, 11.8% of 6087 participants reported a perceived need for treatment due to mental health problems. In 2016, the prevalence increased significantly to 14.0% of 6110 participants. Of those who reported a perceived need for treatment, 36.4% in 2014 and 36.9%in 2019 did not see a psychotherapist - where rates of non-utilization of psychotherapy were vastly higher in the oldest age category (59.3/52.5%; 75+) than in the youngest (29.1/10.7%; aged 18-25). Concerning factors associated with non-utilization, multivariate findings indicated participation in the cohort of 2014 (OR 0.94), older age (55-64 OR 1.02, 65-74 OR 1.47, 75+ OR 4.76), male gender (OR 0.83), lower educational status (OR 0.84), rural residency (OR 1.38), single habiting (OR 1.37), and seeing a GP (OR 1.39) to be related with non-utilization of psychotherapy; general health status was not significantly associated with non-utilization when GP contact was included in the model. CONCLUSION: There is a strong age effect in terms of non-utilization of outpatient psychotherapy. Individual characteristics of both healthcare professionals and patients and structural barriers may add to this picture. Effective strategies to increase psychotherapy rates in those older adults with unmet treatment needs are required.

Depressed Older Patients with Death Wishes: Experimental Evidence for Psychotherapists' Age and Health Bias.

Objectives: When psychotherapists encounter an older patient with depression and death wishes, especially when burdened by physical illness, they may be subject to judgmental biases. This study investigates how this group of patients with highest suicide risk may experience discrimination both on age and health status. Methods: Using a 2 × 2 [chronological age x physical health status] vignette design, psychotherapists (N = 147) were randomly presented with one of the four variants of a case describing a patient with depression and death wishes (i.e., 78 years old + poor physical health; 78 years old + normal physical health; 48 years old + poor physical health; 48 years old + normal physical health). Afterward, participants' attitudes toward the case were assessed. Results: In case of the hypothetical patient's old age and poor health status, participants did not underestimate the pathological significance of his death wishes, but nevertheless showed less optimistic treatment attitudes and less confidence in psychotherapeutic treatment. Conclusions: Psychotherapists' age bias and health bias may serve as two potentially fatal factors influencing the provision of mental health services. Clinical Implications: Psychotherapists may contribute to better mental health-care provision of older adults with depression and the prevention of late-life suicide by increasing awareness of their age and health bias.

Views on ageing: a lifespan perspective.

Views on ageing (VoA) have special relevance for the ageing process by influencing health, well-being, and longevity. Although VoA form early in life, so far, most research has concentrated on how VoA affect later middle-aged and older adults. In this theoretical article, we argue that a lifespan approach is needed in order to more fully understand the origins of VoA, how they change over ontogenetic time, and how they shape development across the full breadth of the lifespan. We begin by explicitly linking VoA to fundamental principles of lifespan development. We review existing theories of VoA and discuss their respective contributions and limitations. We then outline a lifespan approach to VoA that integrates existing theories and addresses some of their limitations. We elaborate on three core propositions of a lifespan approach to VoA: (1) VoA develop as the result of a dynamic, ongoing, and complex interaction between biological-evolutionary, psychological, and social-contextual factors; however, the relative importance of different sources changes across the lifespan; (2) VoA impact development across the whole lifespan; however, different outcomes, mechanisms, and time frames need to be considered in order to describe and understand their effects; and (3) VoA are multidimensional, multidirectional, and multifunctional throughout life, but their complexity, meaning, and adaptivity change across the lifespan. We conclude with recommendations for future lifespan research on VoA.

The uniqueness of subjective ageing: convergent and discriminant validity.

Although a large body of research has demonstrated the predictive power of subjective ageing for several decisive developmental outcomes, there remains some controversy about whether subjective ageing truly represents a unique construct. Thus, information about the convergent and discriminant validity of different approaches to measuring subjective ageing is still critically needed. Using data from the 2014 wave of the German Ageing Survey, we examined how three established subjective ageing measures (subjective age, global attitude toward own ageing, multidimensional ageing-related cognitions) were inter-related as well as distinct from general dispositions (optimism, self-efficacy) and well-being (negative affect, depressive symptoms, self-rated health). Using correlational and multivariate regression analysis, we found that the three subjective ageing measures were significantly inter-related (r = |.09| to |.30|), and that each measure was distinct from general dispositions and well-being. The overlap with dispositional and well-being measures was lowest for subjective age and highest for global attitudes towards own ageing. The correlation between global attitudes towards own ageing and optimism was particularly striking. Despite the high convergent validity of the different dimensions of ageing cognitions, we nevertheless observed stronger associations between specific dimensions of ageing cognitions with negative affect and self-rated health. We conclude that researchers should be aware of the multidimensional nature of subjective ageing. Furthermore, subjective age appears to be a highly aggregated construct and future work is needed to clarify its correlates and reference points.
