“…Therefore, the study first included 332 participants and the final sample size was 274 participants, after the attrition of the participants. Incrementing the initial sample calculation is common practice in longitudinal studies and is widely recommended since the major problem when conducting this study is the attrition (Mazen et al, 2019). Increasing the sample size by 10% is an acceptable value according to the literature (Pullenayegum et al, 2021).…”

Introduction Cancer patients are exposed to several types of treatments, including chemotherapy. In this context, patients experience several nursing diagnoses, including spiritual distress. The definition of the diagnosis of spiritual distress is grounded in lack of meaning and purpose in life, a sense of suffering, and a feeling of disconnected. Purpose The aim of this study was to determine the prevalence, sensitivity, specificity, and predictors of the nursing diagnosis of spiritual distress of cancer patients undergoing chemotherapy. Designs The study used a longitudinal questionnaire design with quarterly data collection points over a 12‐month period. Participants were recruited through random sampling, in an outpatients' setting in one oncology day unit in Portugal. Findings The highest prevalence of spiritual distress was found at 3 months after patients started chemotherapy. The highest value of specificity was lack of meaning in life and express suffering, and the highest values of sensitivity concerned spiritual distress diagnosis. The predictors of spiritual distress were express suffering, alienation, questioning meaning in life, lack of serenity, questioning the meaning of suffering, hopelessness, and lack of meaning in life. Conclusions Spiritual distress is a human response that is current in patients undergoing chemotherapy, and the highest prevalence seems to occur at 3 months after commencing chemotherapy. Express suffering and lack of meaning in life play the role not only of defining characteristics (DC) in this study, but also of predictors in the diagnosis of spiritual distress. Clinical Relevance The identification of the prevalence, predictors, sensitivity, and specificity of the DC of the nursing diagnosis of spiritual distress in cancer patients undergoing chemotherapy may facilitate nurses' clinical reasoning and improve the planning of nursing care in clinical practice in order to improve spiritual well‐being in cancer patients.

“…Researchers in the past have used some forms of hybrid designs. For example, Mazen, Tong, and Taylor (2019) used a PMD design to collect supplemental samples for a complete data longitudinal design when the planned data collection encountered high attrition (i.e., a large amount of unplanned missing data).

Longitudinal panel studies are widely used in developmental science to address important research questions on human development across the lifespan. These studies, however, are often challenging to implement. They can be costly, time-consuming, and vulnerable to test-retest effects or high attrition over time. Planned missingness designs (PMDs), in which partial data are intentionally collected from all or some of the participants, are viable solutions to these challenges. This article provides an overview of several PMDs with potential utilities in longitudinal studies, including the multi-form designs, multi-method designs, varying lag designs, accelerated longitudinal designs, and efficient designs for analysis of change. For each of the designs, the basic rationale, design considerations, data analysis, advantages, and limitations are discussed. The article is concluded with some general recommendations to developmental researchers and promising directions for future research. K E Y W O R D S accelerated longitudinal designs, efficient designs, longitudinal studies, multi-form designs, planned missingness designs, twomethod designs, varying lag designs Longitudinal panel studies (also termed longitudinal survey studies) are widely used in developmental science to address important research questions on human development across the lifespan. Longitudinal panel studies involve repeatedly collecting measures of target outcomes (e.g., emotional outcomes, gender identity, child abuse, problematic

ObjectiveSelf‐criticism has been proposed as a transdiagnostic predictor of disordered eating and nonsuicidal self‐injury (NSSI). First, this study explored cross‐sectional associations of multiple disordered eating behaviors, NSSI, and self‐criticism. Second, it tested longitudinal relations of self‐criticism with disordered eating and NSSI, adjusting for baseline levels of both behaviors.MethodsIn Sub‐study 1, undergraduates (N = 251, 79.5% female, Mage = 19.1 years) completed self‐report measures of disordered eating, NSSI, and self‐criticism at baseline and after 8 weeks. In Sub‐study 2, community‐based young adults with histories of disordered eating, NSSI, or both (N = 517, 88.8% female, Mage = 24.7 years) completed measures of disordered eating, NSSI, and self‐criticism at baseline and after 4 weeks. All measures were completed online.ResultsIn Sub‐study 1, both disordered eating and NSSI showed significant cross‐sectional associations with self‐criticism, and self‐criticism was significantly related to binge eating, fasting, and NSSI at follow‐up. In Sub‐study 2, both behaviors again showed significant cross‐sectional associations with self‐criticism. Self‐criticism showed significant longitudinal relations with fasting, purging, and excessive exercise. Longitudinal relations of self‐criticism with NSSI varied across disordered eating behaviors.DiscussionNSSI showed cross‐sectional associations with a range of disordered eating behaviors. Self‐criticism reflects a common correlate of both disordered eating and NSSI. Evidence supported transdiagnostic longitudinal impact of self‐criticism across multiple forms of disordered eating but provided more limited support for impacts on NSSI.
