Because shepherding is one of the oldest occupations of humanity, the metaphor of the shepherd as leader dates back thousands of years and is a universal image. Therefore, the shepherd leader metaphor is an ideal vehicle through which to study leadership. The Shepherd Leadership Inventory (SLI) measures the degree to which individual leaders are leading as shepherd leadership in the workplace. Through the initial study of the shepherd leader metaphor beginning with the Scriptures and continuing through modern authors, it was determined shepherd leaders are leaders who insure the wellbeing of their followers through the three primary leader behaviors of guiding, providing, and protecting. The Shepherd Leadership Inventory (SLI) incorporates items to assess these behaviors and was validated through the use of principal component factor analysis. This chapter discusses the background and development of the SLI including reporting on the reliability and validity of the instrument. The results of the inventory are discussed along with commentary on the SLI’s relevance to researchers and practitioners. Information regarding cost and location, as well as additional reading recommendations, is included.

Moderate Dementia

The Quality of Life-Alzheimer’s Disease (QOL-AD) questionnaire is a reliable, valid and popular outcome measure in dementia related studies. However, to date there is no published report on adopted version of QOL-AD in Malay language. Thus this preliminary study aimed to evaluate the reliability and validity of the QOL-AD in Malay language for patients with dementia and to examine the level of agreement between patient-caregiver as a proxy reports on patient’s quality of life. A total of 65 patients with mild to moderate dementia and their caregivers were recruited from the psycho-geriatric clinic, Universiti Kebangsaan Malaysia Medical Centre using a cross sectional study design. The QOL-AD was translated into Malay language using the standard guidelines for cross-cultural adaptation of measure. The patient-caregiver dyads completed the QOL-AD in Malay language separately. Test-retest and internal consistency was evaluated for reliability and construct validity was tested with principal component factor analysis. The reliability of QOL-AD in Malay language was good with Cronbach alpha coefficients of 0.82 and 0.79 and intraclass correlation coefficients of 0.77 and 0.89 for patients and caregivers report respectively. Meanwhile a positive moderate agreement was achieved between patient and caregiver rating (r=0.60, p<0.01). The principal component factor analysis extracted 4 factors for both patient and caregiver reports which explained 66.02% (patients’ report) and 64.24% (caregivers’ report) of the total variance of the scale. As a conclusion, the QOL-AD in Malay language is a reliable and valid tool to measure the quality of life of people with mild to moderate dementia.

The incidence of clinically apparent asymmetric profiles of neuropsychological deficits in Alzheimer's disease (AD) patients similar to those reported in the PET literature is currently unclear. This study investigated lateral neuropsychological asymmetry using principal component factor analysis in a sample of 153 patients diagnosed with probable AD. Using factor scores, patients were classified into groups exhibiting asymmetric or symmetric profiles of neuropsychological deficits. In the analysis of lateral asymmetry, 27.5% of patients were classified as asymmetric (10% verbally and 17% visuospatially). Consistent with reports of continued asymmetry beyond the mild dementia stage, asymmetry was exhibited in the mild, moderate, and severely demented groups. These findings of neuropsychological asymmetry across stages of dementia are consistent with the picture of significant neuropsychological heterogeneity in AD that has been emerging in the decade.

Strong Orientation

This study presents a tourist ecological orientation (TEO) construct based on the responses of participants who were asked to state the importance of various ecological features of planned tourist sites. The higher the TEO score, the more sensitive the person's attitudes toward the ecological requirements and responsibilities of tourist sites. A principal component factor analysis reveals two alternative dimensions of the TEO concept: ‘destination oriented’ and ‘visitor oriented’. The higher score that was given to the latter dimension supports the argument that successful implementation of ecological values at tourist sites requires a strong orientation towards consumer needs in addition to an ideological commitment to the environment. In addition, differences in ecological orientation patterns and structure were analysed along age and nationality.

In this study, 42 school phobic youngsters aged 11 to 15 were investigated to find out if they were exceptionally dependent, particularly on their mothers, as had repeatedly been asserted in connection with similar cases, often without adequate supporting evidence of an objective nature (Berg, 1970). TheHighlands Dependency Questionnaire(H.D.Q.) was administered to their mothers around the time they were accepted for admission to an adolescent psychiatric in-patient unit. The Questionnaire had previously been found to measure at least two unrelated sorts of dependency, represented by a sociability factor (I) and an immaturity factor (III) with satisfactory reliability and validity; this emerged when a principal component factor analysis was performed on the results of applying it to the mothers of a randomly selected sample of 68 secondary school children from the general population, stratified for age, sex and social class (Berget al., 1971). Data on 14 variables was processed on the University of Leeds English Electric KDF9 computer, using a system of standard programmes (Hamiltonet al., 1965). In addition to the two setsof factorscores which were calculated using actual raw score weights, two corresponding sets ofsubscalescores were calculated using approximate raw score weights; correlations between factor and subscale scores in the control group had been found to be: r = ·87 for sociability and r = ·84 for immaturity (Berget al., 1971), whereas in 19 youngsters out of the school phobic group, looked at in another context, they were: r = ·51 for sociability (perhaps explained by a divergence between at least two tendencies which have different emphasis in the factor and subscale scores) and r = ·95 for immaturity. The criteria adopted for the diagnosis of school phobia had been given previously when 29 school phobic cases with similar clinical features were reported in some detail (Berget al., 1969).
