Caregiver Report

AbstractSocially indiscriminate attachment behavior has been repeatedly observed among institutionally reared children. Socially indiscriminate behavior has also been associated with aggression and hyperactivity. However, available data rely heavily on caregiver report of indiscriminate behavior. In addition, few studies have been conducted with samples of home-reared infants exposed to inadequate care. The current study aimed to develop a reliable laboratory measure of socially indiscriminate forms of attachment behavior based on direct observation and to validate the measure against assessments of early care and later behavior problems among home-reared infants. Strange Situation episodes of 75 socially at-risk mother–infant dyads were coded for infant indiscriminate attachment behavior on the newly developed Rating for Infant–Stranger Engagement. After controlling for infant insecure–organized and disorganized behavior in all analyses, extent of infant–stranger engagement at 18 months was significantly related to serious caregiving risk (maltreatment or maternal psychiatric hospitalization), observed quality of disrupted maternal affective communication, and aggressive and hyperactive behavior problems at age 5. Results are discussed in relation to the convergent and discriminant validity of the new measure and to the potential utility of a standardized observational measure of indiscriminate attachment behavior. Further validation is needed in relation to caregiver report measures of indiscriminate behavior.

Comparison Measures

Abstract. The current study examined the validity of two self-report measures of social anxiety constructed using social comparative referent points. It was hypothesized that these comparison measures would be both reliable and valid. Results indicated that two different comparative versions – one invoking injunctive norms and another invoking descriptive norms – showed good reliability, excellent internal consistency, and acceptable convergent and discriminant validity. The comparative measures also predicted positive functioning, some aspects of social quality of life, and social anxiety as measured by an independent self-report. These findings suggest that adding a comparative reference point to instructions on social anxiety measures may aid in the assessment of social anxiety.

St George's Respiratory Questionnaire

Tuberculosis (TB) is one of the disease as the highest contributor to the disease burden in Indonesia. Tuberculosis can affect the patients’ quality of life, such as psychological, physical, and social functioning. St. George's Respiratory Questionnaire (SGRQ) is a special instrument which was widely used to measure the patients’ quality of life with respiratory disease. The objective of this study was to validate the Indonesian version of the SGRQ as instrument to collect data. A descriptive cross section design with 61 subjects was conducted at the Pulmonary Clinics and Primary Health Centers in the region of Yogyakarta within 3 months. The validation process included the known group validity, convergent and discriminant validity and factor analysis. There were 14 items question numbers which did not meet the criteria for convergent validity and 9 items which did not meet the criteria for discriminant validity. Known group validity analysis on gender showed that of the three domains of SGRQ, the activity domain gave statistically significant result. The factor analysis showed the result of Kaiser Meyer Olkin analysis (KMO) was less than 0.5. With a few modifications, the Indonesian version of SGRQ is valid and reliable for measuring quality of life in tuberculosis patients.

Convergent And Discriminant Validity

The aim of this study was to establish the psychometric properties of the new Relationship Satisfaction (RS) scale. Two population based samples were used: The Norwegian Mother and Child Cohort Study (MoBa, N=117,178) and The Quality of Life study (N=347). Convergent and discriminant validity was investigated in relation to the Quality of Marriage Index (QMI), the Satisfaction With Life Scale (SWLS), Relationship Satisfaction of partner, Big Five personality traits (IPIP50) and future relationship dissolution. The full scale with ten items (RS10) and a short version with five items (RS5) showed good psychometric properties. The scale has high internal and test-retest reliability and high structural, convergent, and discriminant validity. Measurement invariance across gender was established. Additionally, predictive validity was evidenced by prediction of future relationship dissolution. We conclude that the RS scale is highly useful as a generic measure of global relationship satisfaction.

AbstractTo demonstrate the measurement properties of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Hepatocellular Carcinoma 18-question module (EORTC QLQ-HCC18) within a previously treated, unresectable hepatocellular carcinoma (HCC) clinical trial population that was distinct from the published QLQ-HCC18 validation population. Analyses were conducted using data from BGB-A317-208, an open label, international, clinical trial assessing efficacy and safety of the monoclonal antibody tislelizumab in adult HCC patients. The EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and QLQ-HCC18 instruments were assessed at baseline and weeks 3 and 9 follow-up visits. Per US Food and Drug Administration guidance, psychometric validation of the QLQ-HCC18 included reliability (internal consistency and test–retest), construct validity (convergent and discriminant validity and known-groups validity), ability to detect change, and meaningful within-patient change (MWPC). Known-groups validity and MWPC analyses were also stratified on several pre-defined subgroups. A total of 248 patients were included. Only the QLQ-HCC18 fatigue, nutrition, and index domains demonstrated acceptable internal consistency; acceptable test–retest reliability was found for fatigue, body image, nutrition, pain, sexual interest, and index domains. The QLQ-HCC18 fatigue domain achieved the pre-specified criterion defining acceptable convergent and discriminant validity for 13 of 16 correlations, whereas the index domain achieved the pre-specified criterion for 14 of 16 correlations. Clear differentiation of the QLQ-HCC18 change scores between improvement and maintenance anchor groups were observed for body image, fatigue, pain, and index domains, whereas differentiation between deterioration and maintenance anchor groups were observed for fever and fatigue domains. MWPC point estimates defining improvement for the QLQ-HCC18 fatigue and index domains were −7.18 and −4.07, respectively; MWPC point estimates defining deterioration were 5.34 and 3.16, respectively. The EORTC QLQ-HCC18 fatigue and index domains consistently demonstrated robust psychometric properties, supporting the use of these domains as suitable patient-reported endpoints within a previously treated, unresectable HCC patient population.

Disease Specific

Quality of life (QoL) is discussed as an additional outcome measure in multiple sclerosis (MS). However, few questionnaires assessing disease specific QoL in MS have been published. On the basis of the literature and interviews with clinicians and MS patients, we have developed a disease specific QoL instrument and validated it in a broad range of patients with MS. In this study, a heterogeneous sample of n=237 MS patients completed the newly developed Hamburg Quality of Life Questionnaire in Multiple Sclerosis (HAQUAMS, in German language) and a battery of already validated questionnaires. They further underwent neurological scoring and objective tests. By these means, we investigated its validity, appropriateness, internal consistency, and retest reliability. Internal consistency and retest coefficients were high and satisfied psychometric standards. Convergent and discriminant validity was supported by direction, magnitude and pattern of correlations with other health measures. HAQUAMS subscales and its total score distinguished between patient groups of varied disease severity, cognitive impairment, and affective symptomatology. No floor or ceiling effects were found in either of the HAQUAMS subscales. The HAQUAMS is a reliable, valid and appropriate instrument for QoL assessment in multiple sclerosis. Data of responsiveness are currently being obtained.
