Assessing the use of back translation: the shortcomings of back translation as a quality testing method

Abstract

Back translation – the ‘re-translation’ of a translated questionnaire back into the original language and the subsequent comparison of the original version and the back translation – is a controversial assessment method for questionnaire translations. Recently, cross-cultural survey methodologists have followed the call for more empirical research on this method. This article adds to the small body of research by drawing on the back translation documentation from the 2012 European Quality of Life Survey (EQLS). First, results from the official EQLS back translation step are contrasted with results when additional persons perform the same comparison step between back translation and original. We note inconsistency in the detection of presumed flaws. Second, the back translation outcome is contrasted with additional native speaker checks of the actual translation. While back translation can uncover problems, it causes quite a number of false alarms, and even more importantly, many problems remain hidden.

A meso measure? Examination of the levels of analysis of the Multifactor Leadership Questionnaire (MLQ)

Critical review of the Multifactor Leadership Questionnaire, Form 5X (MLQ5X), reveals serious problems related to specification of the theoretical level of analysis at which it measures its underlying constructs. Data from two separate samples indicate that items of the commonly used MLQ5X are ambiguous with respect to level of analysis. It appears unclear in many instances whether the items reflect individual, group, or organizational referents. Based upon our analyses and the literature, we present specific propositions concerning the level(s) at which each MLQ5X dimension appears most appropriately conceptualized and measured, along with suggestions for future research and revision of the MLQ5X.

PERCEIVED USEFULNESS OF INFORMATION: A PSYCHOMETRIC EXAMINATION*

The perceived usefulness of information is an important construct for the design of management information systems. Yet an examination of existing measures of perceived usefulness shows that the instruments developed have not been validated nor has their reliability been verified. In this paper a new instrument for measuring two dimensions of perceived usefulness is developed. The results of an empirical study designed to test the reliability and construct validity of this instrument in a capital-budgeting setting are presented.     

Measuring ego-centered social networks on the web: Questionnaire design issues

Collecting survey data on ego-centered social networks is a difficult task, owing to the complex questionnaire format. Usually, the interviewer handles the dynamics of the question–answer exchange, motivates the respondent and ensures the proper recording of the data. Self-administered modes of data collection, especially web data collection, are more problematic, as the respondents are left alone with a complex and burdensome questionnaire. Therefore, questionnaire layout is crucial for ensuring cooperation and data quality. In this paper we examined three key components of the corresponding web questionnaire: the number of name boxes using a single name generator, question format for assessing alter characteristics (i.e. alter-wise vs. question-wise) and number of name interpreters (i.e. alter characteristics). The number of name boxes was found to be essential for the reported size of social networks and also for some aspects of data quality. Specific data quality effects were also found with respect to variations in question format, where question-wise format performed better than alter-wise. The number of name interpreters had a relatively minor effect. Suggestions for possible standardization of the web interface layout are also given, so that equivalence with other data collection modes can be established.     

Psychosocial work environment and mental health among travelling salespeople

Travelling salespeople have a rather unusual working environment, with long periods of absence from their firm and a low level of social contacts with colleagues. Furthermore, they are exposed to high demands in their work, which may conflict with a normal family life. In this paper a cross-sectional study of psychosocial work environment and mental health of Danish travelling salespeople is described. A sample of 1,306 travelling salespeople filled in a questionnaire (response rate 68%). The results indicate that poor mental health is associated with a number of demand indicators: number of working hours per week, number of customers per week, non-day work, and a high level of perceived job demands. On the other hand, the number of hours spent with customers per week is positively associated with mental health. The authors did not find the expected associations between poor mental health and several factors such as number of hours away from firm, nights away from home, and a low degree of perceived support from colleagues and superiors. It is concluded that the main stressors of travelling salespeople are long working hours, many customers, non-day work and high perceived psychological demands in general.     

Good item or bad—can latent class analysis tell?: the utility of latent class analysis for the evaluation of survey questions

Summary.  Latent class analysis has been used to model measurement error, to identify flawed survey questions and to estimate mode effects. Using data from a survey of University of Maryland alumni together with alumni records, we evaluate this technique to determine its usefulness for detecting bad questions in the survey context. Two sets of latent class analysis models are applied in this evaluation: latent class models with three indicators and latent class models with two indicators under different assumptions about prevalence and error rates. Our results indicated that the latent class analysis approach produced good qualitative results for the latent class models—the item that the model deemed the worst was the worst according to the true scores. However, the approach yielded weaker quantitative estimates of the error rates for a given item.     

The four-dimensional symptom questionnaire (4DSQ): measuring distress and other mental health problems in a working population

In non-clinical (working) populations it is important to differentiate between general distress, on the one hand, and psychiatric symptoms—depression, anxiety and somatization—on the other hand. The Four-Dimensional Symptom Questionnaire (4DSQ) is a new instrument that measures these four symptom dimensions (Terluin, ). This study aimed to investigate the psychometric properties of the 4DSQ in a working population. A postal stress and health survey was sent to all employees of a Dutch telecom company, 51% of whom responded (N=3852). The mailing included the 4DSQ, a set of questionnaires concerning job stress (e.g. psychological demands), coping style (e.g. problem-focused coping, avoidant coping), and indicators of strain (e.g. emotional exhaustion, fatigue). Cronbach's α for the four sub-scales of the 4DSQ ranged from .79 to .90. Factor analysis showed four factors corresponding to the four scales of the 4DSQ: distress, depression, anxiety, and somatization. The validity of the 4DSQ was assessed using (partial) correlations with job stress, coping, and strain. As expected, the distress scale showed the strongest correlations with the indicators of strain, as well as with job stress and coping. In conclusion, the 4DSQ is a reliable and valid instrument that can be used in a working population to distinguish between stress-related symptoms and psychiatric illness.
