  • Linear association between frailty as assessed by the Kihon Checklist and quality of life in community-dwelling older adults: A cross-sectional population-based study

     View Summary

    Social networking services (SNSs) are useful tools; however, problematic use leads to mental health problems. This study aimed to examine whether SNS addiction is associated with occupational dysfunction while considering the effects of depression. This cross-sectional study included 268 undergraduates who responded to the questionnaire on the frequency and time of SNS use, the Center for Epidemiologic Studies Depression Scale (CES-D), SNS-X scale, and the Classification and Assessment of Occupational Dysfunction (CAOD). Hierarchical multiple regression analysis showed effect of the SNS-X score for Instagram was significant (β = 0.174, p = .001) adjusted by the CES-D total score. However, the effect of frequency and time of SNS use were not significant. This suggests that SNS addiction, and not SNS use, is a factor associated with occupational dysfunction that should be emphasized and depression.

     View Summary

    Aim This study aimed to investigate the association between occupational participation and depressive symptoms among middle-aged adults in Hokkaido, Japan. Methods Community-dwelling adults aged 40–64 years were recruited using snowball sampling, and 165 participants who returned the questionnaires and met the selection criteria were included in the analysis. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. Occupational participation, including three domains (leisure, productivity, and self-care) and three aspects (occupational control, occupational balance, and satisfaction of performance), was assessed using Self-completed Occupational Performance Index (SOPI) questionnaire. Results Multivariate-adjusted regression analysis revealed that depressive symptoms were associated with lower occupational participation in the productivity domain (β = −0.34, p < .001), whereas analysis of each aspect of the SOPI showed a significant association of depressive symptoms with lower occupational control in productivity domain (β = −0.33, p < .001), occupational balance in productivity domain (β = −0.25, p < .001), and satisfaction with performance in leisure domain (β = −0.16, p = .045) and productivity domain (β = −0.35, p < .001). Conclusion Depressive symptoms was significantly associated with low occupational participation in productivity domain in middle-aged adults. In the domains of leisure and self-care, significant associations were found only between depression symptoms and satisfaction of performance. Occupational therapy interventions for middle-aged adults targeting the maintenance and improvement of participation in productive activities may help preventing depressive symptoms.

  • Development of the Self-Assessment Self-Disclosure Questionnaire to Examine the Association between Self-Disclosure and Frailty among Community-Dwelling Older Adults in Japan

     View Summary

    Self-disclosure is the attitude of communicating one’s experiences and condition to others and is an indicator of mental health and an open personality. Frailty, characterized by reduced physical and psychological resistance, predicts the incidence of dependency and mortality. Although low self-disclosure may be associated with frailty, there is no scale to measure older adults’ self-disclosure. This cross-sectional study assessed the validity of a self-assessment self-disclosure questionnaire and examined the association between the content of self-disclosures to friends and acquaintances and frailty among community-dwelling older adults. A total of 237 adults aged ≥65 in Japan were surveyed using a mailed self-administered questionnaire in 2021. The self-disclosure scale consisted of 10 items and showed adequate validity. Participants were classified into a robust group (n = 117, women 57.3%) and a frailty group (n = 120, women 73.3%) using the Kihon Checklist. After adjusting for covariates, multivariate-adjusted logistic regression models revealed frailty was associated with lower self-disclosure of recent positive events, motivation and strengths (indicating strong points) in life, relationships with family and relatives, experiences of work and social activities, and financial status. The proposed questionnaire must still be further tested in other populations, but our initial results may contribute to preventing frailty and improving mental health among community-dwelling older adults.

    1.本研究の目的と平成30年度の作業予定 メタ認知尺度に関する先行研究例、およびautism spectrum disorder(ASD)を持つ人のインタビューデータからメタ認知に関する三宮の定義を踏まえて尺度項目を抽出し、試作版の尺度を作成する。また、併せてASDの就労支援に活用できるメタ認知トレーニングの開発に着手する。
    2.実施結果 メタ認知尺度の作成に向け、三宮の分類に基づき「人間の認知特性についての知識」、および「メタ認知モニタリング」と「メタ認知的コントロール」に該当する尺度項目の抽出と整理を引き続き実施した。Teasdaleらによるメタ認知的知覚の評定基準も参照しながら抽出基準の検討と尺度項目の整理を進めた結果、三宮に分類に基づく三次元の尺度を想定するのか、メタ認知活動に限定する二次元もしくは一次元尺度とするかという尺度構成の見直しを含め、引き続き検討が必要と判断した。また、尺度項目によっては研究者間で解釈の異なるものがあり、ワーディングの詳細な検討も必要となっている。一方、尺度の検討と併せて就労支援を目的としたメタ認知トレーニング法の開発に着手した。開発に当たっては、既存のトレーニング法として、統合失調症を対象としたメタ認知トレーニングMetacognitive Training(MCT)、うつ病を対象としたD-MCT、および自己調節実行機能モデル(Self- Regulatory Executive Function Model:S- REF)に基づくメタ認知療法 (Metacognitive. Therapy:MCT)等を参照し、さらにASDの診断基準、障害特性を踏まえて基本的な構成を検討している。

     View Summary

    We conducted the following activities: (1)providing parent support programs in mental clinics; (2)establishing a location for study participants to tell their opinions to community supporters; (3)survey on cognitive functioning and parenting activities; (4)a survey on the usefulness of oxytocin as an evaluation index for parenting support. Through the support program, participants showed improvements parenting attitudes. Through the participation in feedback activities, participants showed increases in behaviors of supporting others, and community supporters developed a raised awareness of the importance of support to focus on the strengths. However, parents had parenting experience with low care, and the characteristics of the cognitive functioning related to inadequate parenting attitudes. It is necessity to develop programs for dialogue about their parenting experiences and for cognitive function training. In addition, oxytocin seemed to be effective for evaluation indicators.

     View Summary

    This study investigated the characteristics of social cognition, neuro-cognition and social maladjustment, as well as the relationships among them, in people with Asperger syndrome (AS) and analyzed social maladjustment using a text-mining approach based on the frame of reference of AS. The results suggested that specific social maladjustments were possibly analogous to the cognitive characteristics of AS. The maladjustment has been suggested to occurs when the rather logical and appropriate reasoning in AS is no longer able to deal with illogical problems of neuro-typical such as situation-dependent, likes- and dislikes-dependent, naive cynicism.
