- The Minimal Insomnia Symptom Scale (MISS) is a three-item screening instrument that has been found to be psychometrically sound and capable of screening for insomnia among adults and older people. This study aimed to test the measurement properties of the MISS together with an additional item focusing on daytime functioning among adolescents using the Rasch measurement model.

- Introduction : The Minimal Insomnia Symptom Scale (MISS) is a three-item screening instrument that has been found to be psychometrically sound and capable of screening for insomnia among adults and older people. This study aimed to test the measurement properties of the MISS together with an additional item focusing on daytime functioning among adolescents using the Rasch measurement model. Materials and Methods : A cross-sectional design were used, and data from adolescents (age 13-17 years, n=3022) was analyzed using the Rasch measurement model. Results : The MISS had good measurement properties. When replacing the original MISS item “not rested by sleep” with the item “daytime disturbance”, the measurement properties slightly improved. We label this new scale the MISS-Revised (MISS-R). The reliability was significantly better for the MISS-R (0.55) compared to the MISS (0.50). The optimal cut-off was found to be >6 points, both for the MISS and the MISS-R. Conclusions : This study provides general support that both the MISS as well as the MISS-R have good fit to the Rasch model. At this stage, neither the MISS nor the MISS-R can be advocated over the other for use among adolescents, although the MISS-R had slightly better reliability than the MISS. Additional studies are needed to determine the clinically optimal cut-off score for identification of insomnia.

- Introduction: Magnetic resonance imaging (MRI) is an important modality in diagnostics and treatment follow-up. However, MRI can be perceived as unpleasant even though the examination is non-invasive. Patients' knowledge of the MRI procedure is usually scarce, which may enhance patient anxiety at examination. We investigated the effects on anxiety and satisfaction with an information booklet on MRI compared to a placebo booklet delivered to adult patients prior to their first MRI examination. Methods: This randomized, single-blind, placebo-controlled trial included 197 patients. The intervention group (n = 95) received a booklet about MRI prior to the examination, whereas the control group (n = 102) received a placebo booklet of the same size and layout but containing general information. The State Trait Anxiety Inventory with supplementary questions from the Quality from the Patient's Perspective questionnaire were used as patient-reported outcome measures. Results: Anxiety did not differ between the groups, either prior to MRI or during the examination, but those who received the placebo booklet were at higher risk of experiencing high anxiety prior to the MRI examination (odds ratio 2.64; P = 0.029). The intervention group was more satisfied with the information received (P = 0.044), and a majority of participants in both groups (≥87%) considered it important to obtain information on the MRI procedure. Conclusion: Written MRI information decreases the risk of high anxiety levels before MRI and improves patient satisfaction with the information. Further research is needed to investigate whether written information prior to MRI is beneficial not only from the perspective of the patient but may also be cost-effective. Implications for practice: Written MRI information prior to the examination is recommended in radiography care.

- BACKGROUND AND PURPOSE: The Unidimensional Fatigue Impact Scale (U-FIS) was developed for use in a multiple sclerosis population. The aim was to determine whether the U-FIS is a valid tool for measuring the impact of fatigue in Crohn's disease (CD). METHOD: CD patients completed the U-FIS as part of a validation study of the Crohn's Life Impact Questionnaire (CLIQ). Data were analyzed according to Rasch measurement theory (RMT). RESULTS: Two hundred sixty-one completed U-FIS questionnaires were available for analysis. After rescoring the items to resolve disordered thresholds, all 22 items showed acceptable RMT fit. However, there was considerable local item dependency (LID). CONCLUSION: The U-FIS did not provide unidimensional measurement in a sample of CD patients due to high levels of LID. Combining the three FIS outcomes into a single measure was not justified.

- AIM: Informal caregivers play a vital role in the care of people with Alzheimer's Disease (AD), yet caregiving is associated with caregivers' burden. The initial objective of the study was to develop a new outcome measure to assess quality of life (QoL) in AD caregivers. METHODS: Informal (non-professional) caregivers providing 75% or more of the care activities for, and living in the same household as, a person with AD were invited to take part in the study. Qualitative interviews (N = 40) were conducted with AD caregivers in the UK and thematic analyses were applied to generate a pool of potential items. A draft questionnaire was produced and adapted for use in Italy, Spain, Germany and the US. In each of the 5 countries, cognitive debriefing interviews (N = 76) were conducted to determine the questionnaire's face and content validity, followed by a postal validation survey (N = 268). The data from these surveys were combined to reduce the number of items and assess the new questionnaire's psychometric properties. RESULTS: Thematic analysis of the UK interview transcripts generated a draft questionnaire, which was successfully translated into each additional language. The items were well accepted and easy to complete. However, reanalysis of the qualitative interview data revealed that spousal and non-spousal caregivers identified different experiences of caregiving. A review of the item pool indicated that items were primarily targeted at spousal caregivers. Therefore, further analyses of the postal survey data included spousal caregivers only (n = 116). The results supported scaling assumptions (e.g., corrected item-total correlations ≥0.32), targeting (e.g., floor/ceiling effects <2.5%), internal consistency (α ≥0.93) and test-retest reliability (rs = 0.88) of the new questionnaire, according to classical test theory. Assessment of external construct validity yielded results in accordance with a priori expectations. QoL scores were most strongly related to scores on the emotional reactions sections of the Nottingham Health Profile and the General Well-Being Index. The new questionnaire was found to be capable of detecting meaningful differences between respondents; spousal caregivers had worse QoL when the person with AD was confused (p < .001), could not be left alone (p < .001), did not recognize the caregiver (p < .001), was incontinent (p < .05), and wandered around the house (p = .01). CONCLUSIONS: The Alzheimer's Disease Patient Partners Life Impact Questionnaire (APPLIQue) is a questionnaire specific to spousal caregivers of people with AD. Data support its scaling assumptions and it exhibits excellent psychometric properties according to classical test theory. The questionnaire is recommended for use in intervention studies where the QoL of spousal caregivers is of interest.
