Breathlessness is a common and distressing symptom in older adults and an independent predictor of adverse outcomes. Yet, its multidimensional assessment has not been validated in older adults. We apply and validate the Multidimensional Dyspnoea Profile (MDP) in a sample of adults 75 years and older in Belgium.Breathlessness was rated with the MDP, modified Borg dyspnoea scale, numerical rating scale for intensity and unpleasantness both before and after exertion (the short battery of physical performance tests (SPPB)), as well as with the Medical Research Council dyspnoea scale. The Hospital Anxiety and Depression Scale (HADS) assessed the affective status. Factor structure was analysed with exploratory principal components analysis, internal consistency with Cronbach's alpha and concurrent validity with Spearman's correlation coefficients with other breathlessness scales, HADS and SPPB scores.In 96 participants (mean age: 85 years; 34% men) who rated breathlessness at both assessment points, exploratory principal components analysis identified two components: immediate perception (IP) and emotional reaction (ER) explaining most of MDP item variance (65.37% before and 71.32% after exertion). Internal consistency was moderate to high for MDP-IP (Cronbach's alpha=0.86 before and 0.89 after exertion) and MDP-ER (Cronbach's alpha= 0.89 before and 0.91 after exertion). The correlation patterns of MDP-IP and MDP-ER with other tests confirmed concurrent validity.The domain structure, reliability and concurrent validity of MDP for breathlessness before and after exertion were confirmed in a sample of adults 75 years and older, supporting its use and further research for the multidimensional profiling of breathlessness in older adults.

OBJECTIVE: To develop and test a questionnaire that can be used to measure directive guidance behaviors by pharmacists. QUESTIONNAIRE DESIGN: The Purdue Pharmacist Directive Guidance (PPDG) scale was developed based on the directive guidance dimension of socially supportive behaviors, as described by Barrera and Ainlay. The final scale consists of 10 items. SUBJECTS: Individuals on the Walker Test Crew database who were 18 years of age or older and self-reported taking medications for asthma, hypertension, and/or diabetes in the past 3 months were eligible for inclusion. All data were collected through telephone interviews. A total of 464 contacts were made, resulting in 300 responses. DATA ANALYSIS: Principal components analysis was performed to determine the construct subscales of the PPDG. Internal consistency of the PPDG and its subscales was assessed using Cronbach's alpha and corrected item-total correlations. Pearson product-moment correlations of the PPDG with measures of family and friend support (FFS) and self-reported medication adherence were used to determine convergent validity. Spearman rank-order correlations of the PPDG with the total number of prescription medications as well as those for asthma, hypertension, and diabetes taken in the past 3 months were obtained. ANOVA and Student's t-tests were used to determine differences in PPDG across demographic characteristics. RESULTS: Principal components analysis yielded two subscales for the PPDG. These were named Instruction and Feedback and Goal Setting, based on their content. The PPDG scale had good internal consistency (Cronbach's alpha = 0.86), and correlated positively and significantly with FFS (r = 0.27), giving some evidence of convergent validity. The PPDG scale and its subscales also had logically intuitive positive and significant correlations with the total number of prescription drugs taken in the past 3 months. CONCLUSIONS: The PPDG is short and easy to administer, and showed validity and reliability. The PPDG scale should be useful in developing a better understanding of the process by which pharmacists influence healthcare outcomes, assessing variations in pharmaceutical care, and as a tool in identifying means of overcoming barriers to higher levels of pharmaceutical care.

Functioning Assessment

Abstract Background Many frequently used instruments fail to assess psychosocial functioning in patients with bipolar disorder. The Functioning Assessment Short Test (FAST) was developed in order to tackle this problem and to assess the main functioning problems experienced by patients with bipolar disorder. However, the original FAST is not fully applicable in older adults due to the domain of occupational functioning. The aim of our study was to validate an adapted version for Older adults (FAST-O) in a group of older adults with bipolar disorder (OABD). Methods 88 patients aged 50 years and over diagnosed with bipolar disorder were included. We adapted the items in the area of “work-related functioning” of the FAST into items assessing “societal functioning”. Several measurements were conducted in order to analyse the psychometric qualities of the FAST-O (confirmatory factor analysis for internal structure, Cronbach’s alpha for internal consistency, Spearman’s rho for concurrent validity, Mann–Whitney U test for discriminant validity). Results Mean age in the study sample was 65.3 (SD = 7.5) and 57.3% was female. The internal structure was most similar to the internal structure of the original FAST. The internal consistency was excellent (Cronbach’s alpha = .93). The concurrent validity when correlated with the Social and Occupational Functioning Assessment Scale was low, but significant. The FAST-O was also able to distinguish between euthymic and symptomatic OABD patients. Conclusions The FAST-O has strong psychometric qualities. Based on our results, we can conclude that the FAST-O is a short, efficient solution in order to replace global rating scales or extensive test batteries in order to assess daily functioning of older psychiatric patients in a valid and reliable manner.

Purpose This study aims at translating and adapting a common and widely used proxy rated cognitive screening tool – Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) into Hausa language and also to evaluate the instrument’s psychometric properties. Design/methodology/approach IQCODE was translated and adapted using a qualitative process involving experts and the adapted version was then evaluated against a gold standard (Diagnostic and Statistical Manual of Mental Disorder V criteria for neurocognitive disorders) with older adults subjects (N = 100), while its reliability (internal consistency) was also evaluated. Descriptive statistics of mean and frequencies, and inferential statistic of receiver operating curve analysis and Cronbach’s alpha coefficient were used for data analysis at an alpha level set at 0.05. Findings The Hausa IQCODE has a sensitivity value of 73.3%, specificity value of 71.8% and optimal cut-off values of between 3.2 and 3.3. For his adapted instrument the area under the Curve (AUC) curve is 0.79 (95% CI: 0.663–0.919; std. err: 0.066; P = 0.000), and Cronbach’s alpha value of 0.819 was obtained indicating that the adapted instrument has good internal consistency. Research limitations/implications The adapted IQCODE is a valid and reliable proxy based cognitive screening tool for the older adult Hausa speakers in Maiduguri. However, clinician and researcher might want to consider different optimal cut-off points when using this tool to screen or to monitor cognitive changes among older adults. Originality/value This research paper translated and adapted Hausa IQCODE into Hausa language. And it gives information on the validity and reliability of the adapted tool alongside with new optimal cut-off for cognitive screening by proxy among older adult patients in Nigeria.

This article reports the findings of a replication and validation study of the factor structure of the recently developed Reminiscence Functions Scale (RFS) [1]. Three hundred and ninety-nine adult subjects ranging in age from seventeen to forty-five years ( M age = 22.7, SD = 5.7) completed the RFS. A principal components analysis indicated the viability of an eight-factor scale which strongly parallels the earlier scale construction. Factors were labeled: Boredom Reduction, Death Preparation, Identity, Problem-Solving, Conversation, Intimacy Maintenance, Bitterness Revival, and Teach/Inform. Internal consistency scores ranged from .74 to .86 and closely duplicated original scores. Age differences on Death Preparation and Teach/Inform were replicated. Potential uses of the RFS are documented.

Depression Scales

The Zemore Depression-Proneness Rating Scale was administered to 208 university students. A principal components analysis with varimax rotation identified three factors representing Negative Self-attitude, Performance Difficulty, and Lack of Appetite. Some similarity between the present factors and those of the Beck Depression Inventory was discussed. Because the scale overemphasizes cognitive components, attention to items on the somatic aspects of depression was suggested. However, it should be noted that depression-proneness appears to be the feature of Zemore's scale that sets it apart from other depression scales.

Participation Motives

Research on variables that encourage older adults to exercise is limited. This study was carried out to identify the participation motives of older Australians involved in regular exercise and sport. The 815 participants (399 men, 416 women) ranged in age from 55 to 93 years (M= 63.6,SD= 7.8) and were participating in their activities of choice at least once per week. All participants completed the Participation Motivation Questionnaire for Older Adults. The most common exercise/sport activities that participants were involved in were walking, golf, lawn bowls, tennis, and swimming. The most highly reported motives for participation were to keep healthy, liking the activity, to improve fitness, and to maintain joint mobility. Principal-components analysis of the questionnaire revealed 6 factors: social, fitness, recognition, challenge/benefits, medical, and involvement. Analyses of variance showed significant differences in reasons for participation in exercise and sport based on gender, age, education level, and occupation.

Aim We aimed to translate and cross-culturally adapt the International Knee Documentation Committee—subjective knee form (IKDC) in Romanian. Method The original (US) IKDC—subjective knee form was translated according to recommended guidelines. Validity was tested using Spearmans’s correlation coefficient between score sand test-retest reproducibility. Reliability and internal consistency were determined using Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC). Results A total of 106 data sets were available for processing. The average age was 52 years and the male to female ratio was 40:66. Fifty-five subjects repeated the form after an average of 4 days. There were no floor or ceiling effects (range 3.4–74.7). There was a strong correlation between the first and repeated administration of the IKDC—subjective knee form (r = 0.816, n = 50) and moderate compared to Tegner-Lysholm knee rating scale (r = 0.506, n = 102), KOOSJR (Knee disability and Osteoarthritis Outcome Score for Joint Replacement, r =  − 0.622, n = 96), EuroqolEQ-5D-5L Index (r = 0.633, n = 100) and visual analogue scale VAS (r = 0.484, n = 99). Internal consistency was moderate with Cronbach’s alpha 0.611 (n = 102) and ICC 0.611 for average measures (95% CI 0.493–0.713). Conclusion The Romanian translation of the IKDC—subjective knee form is a valid, consistent and reproducible outcome measure in patients with knee pain and dysfunction.

SUMMARYThe bacteriological status of beef carcasses was monitored at a commercial abattoir before and after two stages of modernization to the beef slaughterline which included changing from cradle dressing to dressing on an overhead rail, and the introduction of hot water spray cleaning of carcasses. Although small significant (P < 0·05) differences in bacterial count occurred among carcass sites within modernization stages, significant visit within stage variation and stage × site interactions prevented any significant change in overall count being observed among stages and carcass sites. Principal components analysis revealed small changes in the distribution of bacterial numbers on the sites sampled.

We examined the factor structure and internal consistency of the Spanish version of the Gordon Test of Visual Imagery Control, as well as the correlations with scores on the Vividness of Visual Imagery Questionnaire and the Verbalizer-Visualizer Questionnaire, for a sample of 479 undergraduates. Principal components analysis, followed by varimax orthogonal rotation, identified the expected four factors (Movement, Misfortune, Colour, and Stationarity), which jointly explained 55% of the variance. The Gordon Test had a Cronbach α value of .69 and correlated significantly with scores on Marks' Vividness of Visual Imagery Questionnaire.
