    Self-determination, social abilities and the quality of life of people with intellectual disability

    JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 11 2007
    L. Nota
    Summary Background The international literature has documented that self-determination is impacted by environmental factors, including living or work settings; and by intraindividual factors, including intelligence level, age, gender, social skills and adaptive behaviour. In addition, self-determination has been correlated with improved quality of life (QoL). This study sought to contribute to the growing literature base in this area by examining the relationship among and between personal characteristics, self-determination, social abilities and the environmental living situations of people with intellectual disabilities (ID). Methods The study involved 141 people with ID residing in Italy. Healthcare professionals and social workers who had known participants for at least 1 year completed measures of self-determination, QoL and social skills. Analysis of variance was conducted to verify whether different levels of intellectual impairment were associated with different degrees of the dependent variables. The Pearson product,moment correlation was used to examine any relationships among dependent variables and IQ scores. Finally, discriminant function analysis was used to examine the degree to which IQ score, age, self-determination and social abilities predicted membership in groups that were formed based on living arrangement, and on QoL status (high vs. low). Results The anova determined, as expected, that participants with more severe ID showed the lowest levels of self-determination, QoL and social abilities. Discriminant function analysis showed that (a) individuals attending day centres were distinguished from those living in institutions in that they were younger and showed greater autonomy of choice and self-determination in their daily activities; (b) basic social skills and IQ score predicted membership in the high or low QoL groups; and (c) the IQ score predicted membership in the high or low self-determination groups. A manova conducted to examine gender- and age-level differences on self-determination found gender differences; women had higher self-determination scores than men. Conclusions These findings contribute to an emerging knowledge base pertaining to the role of intraindividual and environmental factors in self-determination and QoL. In general, the study replicated findings pertaining to the relative contribution of intelligence to self-determination and QoL, added information about the potential contribution of social abilities, and pointed to the potentially important role of opportunities to make choices as a particularly important aspect of becoming more self-determined, at least in the context of residential settings.

    Coping strategies and health-related quality of life among spouses of continuous ambulatory peritoneal dialysis, haemodialysis, and transplant patients

    JOURNAL OF ADVANCED NURSING, Issue 6 2000

    Coping strategies and health-related quality of life among spouses of continuous ambulatory peritoneal dialysis, haemodialysis and transplant patients In the study reported here 55 spouses of patients living with end-stage renal disease (ESRD) were investigated with respect to coping strategies and health-related quality of life. Findings from the study were compared to two random samples of the Swedish general population (n = 454, and n = 1200). The study design was correlational and comparative. Coping was measured by the Jalowiec Coping Scale, and quality of life (QoL) by the Swedish Health-Related Quality of Life Survey (SWED-QUAL). Data were analysed using a number of statistical tests including Pearson's product moment correlations, Student's t -test and two way ANOVAs. The combined sample of spouses used significantly more optimistic and palliative coping than the general population, but less confrontative, self-reliant, evasive and emotive coping. In the study fatalistic, evasive and emotive coping was associated with low perceived efficiency in handling various aspects of the partners' situation. The male spouses used significantly less optimistic, supportive and palliative coping than did the female spouses. The spouses of transplant patients had better overall quality of life than the continuous ambulatory peritoneal dialysis and haemodialysis spouse groups, most likely due to the lower age of the former group. The study findings suggest that emotive, evasive and fatalistic coping are less than optimal ways to deal with problems occasioned by the partner's treatment. [source]

    Using the cardiac depression scale in men recovering from coronary artery bypass surgery

    JOURNAL OF CLINICAL NURSING, Issue 11 2009

    Aims., To examine the utility and validate the use of the Cardiac Depression Scale in patients who had first-time coronary artery bypass graft surgery. Background., The Beck Depression Inventory, though frequently used, may not be sufficiently sensitive for use in cardiac patients. The Cardiac Depression Scale has been shown to identify the range of depression in medical cardiac patients. Design., Survey. Methods., The Beck Depression Inventory and Cardiac Depression Scale were administered to 120 men at hospital discharge, as well as six, 12 and 36 weeks postoperatively. Cronbach's , scores were calculated for the measures at each point. Changes in scores over time were analysed using repeated measures analysis of variance. Associations between the measures scores were calculated using Pearson product,moment correlations. Agreement between the measures' dichotomised scores (depression/no depression) was examined using Cohen's Kappa statistic. Results., Internal consistency was similar for the Beck Depression Inventory (0·793,0·904) and Cardiac Depression Scale (0·859,0·910). Depression scores decreased over time with the Beck Depression Inventory [F(2·50, 175·29) = 22·27, p < 0·001] and Cardiac Depression Scale [F(2·68, 190·37) = 13·18, p < 0·001]. The measures had similar power [Cohen's f = 0·65 (Beck Depression Inventory) and 0·43 (Cardiac Depression Scale)] to reveal changes over time. The continuous scores were highly correlated at each point [0·737 (p < 0·001),0·819 (p < 0·001)]. However, when dichotomised scores were compared, the chance corrected level of agreement was less impressive [0·198 (p = 0·014),0·381 (p < 0·001)]. Conclusions., The Cardiac Depression Scale may have utility for use with surgical cardiac patients. However, continued examination of this measure of depression is warranted. Relevance to clinical practice., Given the prevalence of depression and its negative impact on coronary artery disease, it is important to identify even mild depression in cardiac patients. Using a measure of depression specifically for cardiac patients, rather than a generic measure, may best accomplish this goal. [source]

    Reliability and validity of the Leisure Satisfaction Scale (LSS , short form) and the Adolescent Leisure Interest Profile (ALIP)

    OCCUPATIONAL THERAPY INTERNATIONAL, Issue 2 2002
    Angela N. Trottier MClSc, OT Reg (Ont) Occupational Therapist
    Abstract This study aimed to evaluate the reliability and validity of the Leisure Satisfaction Scale (LSS , short form) and the Adolescent Leisure Interest Profile (ALIP). The LSS and the ALIP are instruments that occupational therapists can use to evaluate the leisure activities that clients enjoy. Evaluation of leisure interest and participation will assist in creating goals for therapy to maximize a client's ability to participate in leisure activities. This study examined the test,retest reliability and concurrent validity of the LSS and the ALIP using a sample of 37 adolescents between the ages of 13 and 17 with no known impairments. The assessments were administered individually or in small groups 7 to 17 days apart. Cronbach's alpha was used to determine the internal consistency. Pearson product moment correlations were calculated to examine the test,retest reliability of the 60 subscales and the six question totals of the ALIP, as well as for the 6 subscales and total score of the LSS. Concurrent validity was evaluated between the ,How often?' question of the ALIP and the LSS (short form). Based on the study results, the ALIP and the LSS seem to have good test,retest reliability levels when used with adolescents with no known physical or mental impairments. The concurrent validity between the two instruments was not supported, with many of the scores indicating only weak or no association to each of the subscales, suggesting that the assessments differ in some fundamental way. However, the evidence of some relationships between subscales may indicate some areas where the ALIP and the LSS are similar. Copyright © 2002 Whurr Publishers Ltd. [source]
