Think Aloud (TA) studies provide rich verbal data about reasoning during a problem solving task. Using TA and protocol analysis, investigators can identify the information that is concentrated on during problem solving and how that information is used to facilitate problem resolution. From this, inferences can be made about the reasoning processes that were used during the problem-solving task. In the past, the validity of data obtained from TA studies has been suspect because of inconsistencies in data collection and the inability to verify findings obtained from the slow, laborious process of protocol analysis. This article describes a means of obtaining more accurate verbal data and analyzing it in a standardized step-by-step manner.

Reduced nutritional intake with low and decreased body weight can be a component of normal ageing. There is, however, also a greater risk for reduced nutritional intake within certain diagnoses, especially for chronic diseases. Malnutrition in chronic obstructive pulmonary disease (COPD) is caused by many factors. The relationship between COPD and low values of body mass index (BMI) is a known independent risk for mortality. For optimal support and care with special focus on nutritional status and interventions, caregivers need more knowledge about the meal-related situations (i.e. shopping for food, cooking and eating) of COPD patients. The aim of this study was to describe experiences of meal-related situations as viewed from the individual's perspective. The sample included eight women and five men with COPD recruited from five primary health clinics. The participants' average age was 68.9 years, with values of forced expiratory volume in 1 second (FEV(1) percentage) ranging from 18 to 69 and BMI values from 15 to 40. A descriptive design with qualitative interviews and self-reported diaries were used and the data were later analysed using content analysis. Findings showed consistency between informants' COPD, nutritional status and descriptions of experiences in meal-related situations. Findings were disease-specific but were also found to be general- and age-related. Respondents described physical influences and positive and negative feelings in their meal-related situations. Feelings of dependence, level of activity, transport of food, having company or being alone, appetite, hunger and need of time were also mentioned. Most research reports reduced nutritional status from a medical perspective. To our knowledge, no study has reported the positive and negative feelings that arise when eating in persons with COPD. Malnutrition for persons with COPD is not only caused by eating difficulties: eating is an integral part of social situations as shown in this study.

A Think Aloud (TA) method was employed to collect verbal data from seven clinical nurses as they reviewed a written case study and formulated a plan of care. Protocol Analysis (PA) of the verbal data resulted in a visual representation of each subject's plan of care and provided information regarding the clinical data that subjects used to plan care. The results demonstrated that frequently problems and interventions were inextricably linked and considered in unison rather than during separate steps of a planning process. This finding has implications relative to the current practice within both nursing education and nursing service of focusing on problems and interventions separately when planning care.

Asian nurses who are collectivist oriented have become the majority of international nurses working in U.S. hospitals. Collectivists view themselves as members of a group. It is important for administrators to understand workplace-related factors that encourage these nurses to stay. This study examined the relationships among collectivist orientation, perception of practice environment, organizational commitment, and intention to leave. Results demonstrated that organizational commitment is a mediator of perception of practice environment and intention to leave. Implications for administrators are discussed.
