Psychometric properties of the consumer quality index to assess shelter and community care services

Contains fulltext : 153765.pdf (publisher's version ) (Closed access)BACKGROUND: Our aim was to design a valid and reliable consumer quality index (CQI) specifically suited to assess the experiences that homeless people, homeless youth, and abused women have with shelter and community care services. METHODS: A pilot CQI questionnaire was constructed on the basis of literature study, focus group discussions with clients, concept mapping by clients and shelter workers, and a pre-pilot study. The pilot questionnaire was completed by 762 clients using shelter facilities for homeless people, homeless youth or abused women. Psychometric and multilevel analyses were performed to optimize the instrument and determine its validity, reliability and discriminative power. RESULTS: The preparatory research had revealed seven primary focus topics, all of which were incorporated into the pilot questionnaire. Psychometric analyses resulted in four reliable scales, one of which applied only to clients in residential, day or night shelter programs. The final instrument consisted of 42 items for community care clients and 52 for clients using residential facilities, and day and night shelters; 32 and 42 such items pertained to client experiences. CONCLUSION: The consumer quality index for shelter and community care services (CQI-SCCS) is a valid, reliable instrument for assessing the quality of these services. It provides guidance to facilities in quality maintenance and improvement, and it is useful in determining quality differences in facilities for homeless people and homeless youth

Multiple pathways of maternal effects in black-headed gull eggs: constraint and adaptive compensatory adjustment

We investigated in the black-headed gull whether female deposition of antioxidants and immunoglobulins (enhancing early immune function), and testosterone (suppressing immune function and increasing early competitive skills) correlate suggesting that evolution has favoured the mutual adjustment of different pathways for maternal effects. We also took egg mass, the position of the egg in the laying sequence and offspring sex into account, as these affect offspring survival. Yolk antioxidant and immunoglobulin concentrations decreased across the laying order, while yolk testosterone concentrations increased. This may substantially handicap the immune defence of last-hatched chicks. The decrease in antioxidant levels was greater when mothers had a low body mass and when the increase in testosterone concentrations was relatively large. This suggests that female black-headed gulls are constrained in the deposition of antioxidants in last-laid eggs and compensate for this by enhanced testosterone deposition. The latter may be adaptive since it re-allocates the chick’s investment from costly immune function to growth and competitive skills, necessary to overcome the consequences of hatching late from an egg of reduced quality.
