As a health promotion method, health education help improve people’s knowledge of illness, develop their health behavior, increase individual’s sense of responsibility for maintaining health and achieve fully informed consent by the providence of health care information [1–6]. It was reported that if patients were informed about any side effects, possible complications, and the way treatment might affect their daily life, they might establish healthy behaviors and improve self-efficacy [7, 8]. Furthermore, patients can make the right decisions about treatment, correct their wrong beliefs, alleviate psychological comorbidities and thus enhancing their quality of live by being informed about appropriate, valid, and expert health care information [9]. Hence, health care information can also be therapeutic and many patients desire to be given more health-related risk and disease information [10].
Although several studies have documented the various positive impacts of health care information, it has also been evidenced that sometimes the wealth of information available to patients can be as dangerous as it is helpful [11–14]. Deyirmenjian et al. reported that for open-heart patients, the ones with more information providence showed higher levels of preoperative and postoperative anxiety compared with patients almost with no information giving [15]. Montazeri et al. found out that after giving cancer-related information to women in a waiting room at the breast cancer center, they became upset and anxiety [16]. Miller et al. mentioned that when women were exposed to cervical cancer risk information, they might catastrophize health dangers and felt intensely anxious and vulnerable [17]. Doherty-Torstrick et al. reported that for individuals with high illness anxiety, the search for medical information on the Internet made them experience more anxiety [18].
Miller proposed the “Blunting Hypothesis” based on Seligman's safety signal theory, which accounts for individual differences about preference for predictability("monitors") and preference for unpredictability("blunters") under threat [19]. In this theory individuals were categorized into two different coping styles based on their threat-related response: monitors(information seekers) or blunters (information avoiders). When encountering threat-related event, information seekers monitor information and amplify cognitively and emotionally threats, whereas information avoiders avoid and psychologically blunt such cues [20]. In health-related situations, high monitors prefer detailed health-related information and fare better when it is given, and they tend to perceived more risks and show great anxiety or distress when information is not readily available [9, 19]. On the contrary, blunters do better with less information. They cope with aversive health events by distraction, and they tend to make themselves remove from further psychological awareness of disease and their anxiety may be increased when information is supplied too much [19]. Miller mentioned that when patients receive information which match their coping styles, they have better outcomes psychologically, behaviorally and physiologically [21, 22]. It has been evidenced that once the information provided is consistent with individual`s coping style, they will feel less anxious, suffer less complications after surgery, experience shorter hospital length of stay, improve adherence, and show more satisfaction with communication [23–25]. Therefore, patients’ information-seeking styles need to be taken into consideration before providing health care information. The first step is to identify individual variations in information-seeking styles, which requires validated measures of individual information-seeking style preferences.
There exist several scales that can predict information-seeking styles, such as Sentence Completion Test, Repression-Sensitization Scale, Schedule of Recent Experiences [20, 26, 27], among which the Miller Behavioral Style Scale (MBSS) shows good reliability as well as good discriminant and convergent validity compared with other scales.19 The MBSS is a reliable and validated scale, and by far the most extensively used scale for predicting information-seeking style [28–30]. Whether the original scale can be used in population from different social, ethical and cultural backgrounds needs further study. In addition, according to Rees’s [29] literature review of the researches about the MBSS scale, Cronbach`salpha coefficient was rarely reported, and many of the research samples were recruited from students and the sample sizes were small, which limited the generalization of the scale. This study aims to examine the psychometric properties of the MBSS among individuals in Mainland China using a large sample size in medical and non-medical settings.
