“…36 Scale internal consistency reliability was determined by calculating Cronbach coefficient alpha. 37 Scales with reliabilities of 0.70 or greater are recommended for comparing patient groups, whereas a reliability criterion of 0.90 is recommended for analyzing individual patient scale scores.…”

BACKGROUNDThe Pediatric Quality of Life Inventory (PedsQL) is a modular instrument designed to measure health‐related quality of life (HRQOL) in children and adolescents ages 2–18 years. The PedsQL 4.0 Generic Core Scales are multidimensional child self‐report and parent proxy‐report scales developed as the generic core measure to be integrated with the PedsQL disease specific modules. The PedsQL Multidimensional Fatigue Scale was designed to measure fatigue in pediatric patients. The PedsQL 3.0 Cancer Module was designed to measure pediatric cancer specific HRQOL.METHODSThe PedsQL Generic Core Scales, Multidimensional Fatigue Scale, and Cancer Module were administered to 339 families (220 child self‐reports; 337 parent proxy‐reports).RESULTSInternal consistency reliability for the PedsQL Generic Core Total Scale Score (α = 0.88 child, 0.93 parent report), Multidimensional Fatigue Total Scale Score (α = 0.89 child, 0.92 parent report) and most Cancer Module Scales (average α = 0.72 child, 0.87 parent report) demonstrated reliability acceptable for group comparisons. Validity was demonstrated using the known‐groups method. The PedsQL distinguished between healthy children and children with cancer as a group, and among children on‐treatment versus off‐treatment. The validity of the PedsQL Multidimensional Fatigue Scale was further demonstrated through hypothesized intercorrelations with dimensions of generic and cancer specific HRQOL.CONCLUSIONSThe results demonstrate the reliability and validity of the PedsQL Generic Core Scales, Multidimensional Fatigue Scale, and Cancer Module in pediatric cancer. The PedsQL may be utilized as an outcome measure in clinical trials, research, and clinical practice. Cancer 2002;94:2090–106. © 2002 American Cancer Society.DOI 10.1002/cncr.10427

“…The general linear models (GLM) were used to evaluate the significance of interactions with factors while adjusting for sex, age and severity of cord injury. 17 A P-value of o0.05 was taken to indicate statistical significance, and post hoc tests were completed using Scheffe correction to control for the conduct of multiple tests. In addition, Spearman's correlation coefficients were computed to show the correlation between the King's health score and the SF-36 score in patients with SCI.…”

Study design: Cross-sectional study. Objectives: (1) To assess the relationship between bladder management methods and the healthrelated quality of life (HRQL) in patients with spinal cord injury (SCI). (2) To identify any correlation between the two questionnaires used to assess the quality of life (one validated for SCI and one validated for bladder symptoms). Setting: Spinal Cord Injury Centre, Royal National Orthopaedic Hospital, Middlesex, UK. Methods: This study is based on two questionnaires with results collected from 142 people with SCI. The two questionnaires were based on information from the Short-Form 36-Item Health Survey (SF-36) and the King's Health Questionnaire and included demographic characteristics, bladder management methods and the frequency of incontinence. Results: There is a moderate correlation between the results of the SF-36 and the King's Health Questionnaire. Only 21% SCI patients report normal voiding without any other form of bladder management. The type of bladder management may influence the HRQL in patients with SCI. Clean intermittent catheterization by attendant, indwelling transurethral catheterization and indwelling suprapubic catheterization are the three groups with the worst mental status. In addition, the frequency of incontinence is a strong influence on HRQL. Conclusions:The results of this study may provide a general baseline HRQL for patients with SCI. Our findings show the relationships between bladder management methods and quality of life in patients with SCI. In addition, the impact of incontinence on quality of life was also confirmed.

“…Aghajanzadeh et al [17] compared physical function scores from the medical outcomes study 36 short form health survey [34] with the national average (although further details were lacking) and showed these were significantly decreased. Although the symptom definitions were inconsistent between the studies, all reported high frequencies of gastrointestinal symptoms that persisted across all time points assessed.…”

SummaryBackground & aims-As improved outcomes after esophagectomy have been observed over the last two decades, the focus on care has shifted to survivorship and quality of life. The aim of this review was to determine changes in nutrition after esophagectomy and to assess the evidence for extended nutrition support.Methods-A search strategy was developed to identify primary research reporting change in nutritional status a minimum of one month after esophagectomy.Results-Changes in nutritional parameters reported by 18 studies indicated a weight loss of 5-12% at six months postoperatively. More than half of patients lost >10% of body weight at 12 months. One study reported a persistent weight loss of 14% from baseline three years after surgery. Three studies reporting on longer term follow up noted that 27%-95% of patients failed to regain their baseline weight. Changes in dietary intake (three studies) indicated inadequate energy and protein intake up to three years after surgery. Global quality of life scores reported in one study correlated with better weight preservation. There were a high frequency of gastrointestinal symptoms reported in six studies, most notably in the first year after surgery, but persisting up to 19 years. Extended enteral nutrition on a selective basis has been reported in several studies.Conclusions-Nutritional status is compromised in the months/years following oesophagectomy and may never return to baseline levels. The causes/consequences of weight loss/ impaired nutritional intake require further investigation. The role of extended nutritional support in this population remains unclear.
