Theories of Health Change Behaviour
Theories of Health Change BehaviourIntroductionTo understand the  exploites and causes of  flip-flop in wellness  relate behaviours still represents a challenging process for  health professionals (Orleans, 2000). Peoples decisions to engage in such behaviours  argon affected by factors such as attitudes and beliefs and psycho mixer variables (i.e. demographic, psychological or cognitive) which impact the decision-making process of planning behaviours. Thus, it is important to understand the interrelationship between these factors and their  acts of adopting and maintaining healthy behaviours. Researchers have attempted to understand and predict health behaviour through the lenses of models and theories of behaviour change. Within the framework of a  surmisal, the researchers get to understand what variables are  nearly important and how to measure them, to formulate research questions  base on the understanding of the variables, to test hypotheses regarding behaviour change, and las   tly to guiding behaviour change  encumbrances through planning,  operations, and maintenance of preventative behaviours (Noar  Zimmerman, 2005). Theory- base predictors (i.e. cognitive factors) would  supply an unionized framework that helps understand and predict health behaviour in a systematic manner (Glanz  Maddock, 2000).Theories based on processes of cognitions and thoughts are part of the collection of sociable cognitive models (SCMs) and focuses on influences of social-cognitive characteristics on decision-making processes. The present essay distinguishes  dickens of SCMs, highly used in understanding the adoption and maintenance of healthy behaviours the Theory of  good Action (TRA Ajzen and Fishbein 1980) and the Common Sense Model of Self-Regulation (CSM-SR Leventhal, Diefenbach, and Leventhal (1992)). Both theories suggest that the motivation to change behaviour is driven by social-cognitive beliefs/representations of the health threat and the willingness to avoid  waywa   rd outcome. Research applying both theories has a rich history describing their uses in a wide range of behaviours including health (TRA Cooke and French (2008) CSM-SR Hagger and Orbell (2003)). Further, both models are based on a  zeal of theoretical constructs and have been used to successfully explain and change behaviours. Nevertheless, very little research has concerned empirical comparison of the two (Hunter, Grunfeld,  Ramirez, 2003 Orbell, Hagger, Brown,  Tidy, 2006) and there is still no consensus that one model is more accurate than the  another(prenominal).AimThis essays aim was to review two theories of health change behaviour  the Theory of Reasoned Action and the Common Sense Model of Self-Regulation  with special emphasis on the similarities and differences and the data needed to critically compare and  communication channel them. Lastly, the aim was to determine which aspects of the frameworks were most successful at predicting and explaining behaviour.What is health    behaviour?It is the goal of many researchers to understand the causes,  epitopes and processes of health behaviour change (Doll  Hill, 1964). The most  park study looking into the causes of death is the Alameda County Study conducted by Belloc and Breslow in 1972 which identified seven aspects of lifestyle which predicted mortality smoking, alcohol consumption, sedentary lifestyle, sleeping more or less than 8 hours per night, being either underweight or overweight, skipping breakfast, and eating snacks (Belloc  Breslow, 1972). A later British study, the EPIC-Norfolk prospective population study associated similar behaviours with  begin risk of mortality (Khaw et al., 2008).Kasl and Cobb attempted the first definition of health behaviour as any  practise undertaken by a person believing himself to be healthy for the purpose of preventing disease or detecting it at an a prognosticatic stage (Kasl  Cobb, 1966). Although this definition includes only preventive health behaviours there    are other types of behaviours. Ogden (2007) described  malady behaviour as a behavioural action aimed to seek treatment and sick behaviour as a behavioural action aimed to get well (p. 13). There are factors such as   soulistic differences, which influence the change of health behaviours and contributed to the prediction of health behaviours (Baum  Posluszny, 1999 Sherman  Fazio, 1983). The cognitive factors received the most attention because are considered to cause changes in behaviour and because they are modifiable factors in comparison to, for example, personality.The characteristics of social cognitive factors (e.g. knowledge, attitudes, and beliefs) are involved in the process of decision-making and behaviour control (Fiske  Taylor, 1991). SCMs focuse on psychological and social factors and how they influence behaviour change, with a focus on the self-regulation processes and how these relate to behaviour (Conner  Norman, 2005). These models are used to  tally a positive cha   nge in individuals behaviour (e.g., changing food intake or increased physical activity) through  incumbrance (Anderson-Bill, Winett,  Wojcik, 2011). A very known model used to examine individuals reactions to illness threats is Leventhals (1992) the common sense model of self-regulation (CSM-SR). Another theory focused on motivation to perform health-enhancing behaviours by examining aspects of the cognitions to predict health outcomes is the theory of reasoned action (TRA)  intentional by Fishbein  Ajzen (1975). The models mentioned and many other provide a basis for interventions designed to change health-related behaviours through the emphasis of the rationality of human behaviour. Thus, the prediction of behaviour is considered to be the outcome of the intended behaviour based on a rational decisionmaking process.Overview of commonly used modelsTheory of Reason Action (TRA)TRA has been used to predicting the likelihood of performing a  specialised health-related behaviour based    on the compatibility and behavioural intention (Fishbein  Ajzen, 1975 Ajzen  Fishbein, 1980). The model uses cognitive processes of attitudes toward the behaviour (i.e., feeling positive or negative toward the action) and social normative perceptions (i.e., beliefs of  portentous others about the individual performing the behaviour) to predict intention of a behavioural action through a rational decision-making process. The theory has been used in a wide range of fields such as  schooling technology (Mishra, Akman,  Mishra, 2014), software piracy (Aleassa, Pearson,  McClurg, 2010), cyberbullying (Doane, Pearson,  Kelley, 2014), hazing (Richardson, Wang,  Hall, 2012), domestic violence (Sulak, Saxon,  Fearon, 2014), but also in health related behaviour such as substance-abuse (Roberto, Shafer,  Marmo, 2014), physical activity (Plotnikoff, Costigan, Karunamuni,  Lubans, 2013), diet (Middlestadt, 2012), smoking (Lorenzo-Blanco, Bares,  Delva, 2012), HIV prevention behaviours (Jemmott,    2012).Description of the modelThe design of TRA looks at behavioural intentions of an individual in social context, while investigates the relationships between attitudes, intentions and behaviour. Attitudes toward the behaviour are considered to be a comprehensive gathering of evaluations of the behaviour. As a determinant of intentions, attitudes influence peoples perception, thinking and behaviour. Fishbein and Ajzen (1975) have proposed that attitudes should be measured at the same   specialized level as the behaviour. Thus, a high level of specificity in behaviour with regard to action, target, context, and time, will result in a high prediction of outcome behaviour. Individuals attitudes can be explained through the set of beliefs about an outcome of the behaviour and the evaluations (favourable or unfavourable) of the expected outcome. The relationship between salient beliefs and attitudes is based on the Fishbeins (1967) model of summative attitudes, which assumes they infl   uence individuals attitude. The research of  new wave den Putte (1991) and Armitage and Conner (2001) proved a strong link between attitudes and salient behavioural beliefs.Subjective norms are the second determinant of behavioural intention (Ajzen  Fishbein, 1980 Fishbein  Ajzen, 1975). This factor is the representation of the individuals perception of the social pressures from significant others (i.e. family, friends, work colleagues, etc.) about whether he/she should perform a specific behaviour. This is quantified as the product of the normative beliefs (i.e., individuals perceived behavioural expectations of important others regarding the performance of the behaviour) and individuals motivation to comply. Once more, the research of Van den Putte (1991) and Armitage and Conner (2001) identified strong correlations between  inherent norms and normative beliefs.Empirical supportThe TRA has been applied to the prediction of a wide range of different behaviours, including health-rel   ated behaviours, with  variable degrees of success. There are a number of narrative reviews (Albarracin, Johnson, Fishbein,  Muellerleile, 2001 Blue, 1995 Cooke  French, 2008 Godin, Belanger-Gravel, Eccles,  Grimshaw, 2008 Hagger, Chatzisarantis,  Biddle, 2002 Hausenblas  Carron, 1997 Sheeran  Taylor, 1999) as well as a quantitative reviews of the TRA focusing on general and specific behaviours (physical activity (Blue, 1995 Hagger et al., 2002 Hausenblas  Carron, 1997) screening program (Cooke  French, 2008), healthcare professionals (Godin et al., 2008), condom use (Albarracin et al., 2001 Sheeran  Taylor, 1999) and ). and general reviews (Sheppard, Jon,  Warshaw, 1988) van den Putte (1991)). The model has been tested by Sheppard et al. (1988), who reported multiple correlations between intentions and behaviour, and attitudes and subjective norms and intentions to be 0.53 and respectively 0.66 (k= 87, and k=87). Similar results were  represent by van den Putte (1991). These early    studies results constituted the basis of the predictive validity of the TRA framework.In their reviews, Hausenblas and Carron (1997) found a medium  strength size for the relationship of intention and behaviours of 0.47, in 31 studies with a sample size of 10,621. In addition, Albarracin et al. (2001) and Hagger et al. (2002) found the same higher(prenominal) correlation between intention and behaviour (r=0.5). In the most recent review to date, Cooke and French (2008) computed a lower value of r=0.42 in 19 tests of the relationship between intention and behaviour, which is slightly larger than the meta-analytic reports by Godin et al. (2008) (r=0.31, k=15, N=2,112). In conclusion, research provides evidence that there is a considerable  eubstance between TRA variables and their intention to predict behaviour change.Common Sense Model of Self-Regulation (CSM-SR)Description of the modelThe CSM-SR integrates environmental factors and individual beliefs about illness around individuals    common-sense representations of health (Leventhal et al., 1992). The framework outline is based on parallel-processing  ways (Leventhal, 1970). The model is based on two constructs of a) cognitive or objective perpetual pathway with its coping mechanisms and appraisal process and b) affective or subjective pathway which represents the  delirious response to the illness representation with its own coping mechanisms and appraisal processes. The cognitive pathway is based on individuals beliefs or representations of illness threat and comprises five dimensions identity, timeline, cause, consequences, and  recover/control. Moss-Morris et al. (2002) explored the extent to which individuals can evaluate the  coherency of illness representations, or how much individuals comprehend their condition. The pathway uses individuals beliefs to shape the selection of appropriate coping strategies (i.e. approach or avoidance), which in turn are appraised in a repetitive process over time. The self   -regulation process implies selection and monitoring of behaviour aimed at controlling threat conditions and the illness representations are  organise through symptoms perception and social messages from exposure to a wide range of social and cultural factors.A similar process takes place with the subjective or emotional pathway in parallel and in association with the cognitive process just described. The representation of illness triggers the activation of emotional responses regarding health-related behaviours. For example, fear is  actuate when a woman discovers an unusual lump thinking it might be cancer resulting in states of worry and distress. The efforts of controlling the emotional responses are appraised in  terms of their success and lead to refinements of the representation of new coping strategies.Empirical supportUp to date research provides empirical support for the interrelationship between the constructs of identity, timeline, cause, consequences, cure/control, emot   ions, and coherence and health outcomes (coping (Heijmans  de Ridder, 1998 Moss-Morris, Petrie,  Weinman, 1996 Scharloo et al., 2000) and adherence to professional recommendations (Albert et al., 2014 Nicklas, Dunbar,  Wild, 2010)). A series of meta- give outs have now been supported the validity of the CSM-SR framework, including narrative reviews (Hoving, van der Meer, Volkova,  Frings-Dresen, 2010 Kucukarslan, 2012 Lobban, Barrowclough,  Jones, 2003 Munro, Lewin, Swart,  Volmink, 2007) and those focused on specific chronic conditions (diabetes (Hudson, Bundy, Coventry,  Dickens, 2014 Mc Sharry, Moss-Morris,  Kendrick, 2011) acute myocardial infarction (French, Cooper,  Weinman, 2006) and mixed chronic diseases (Hagger  Orbell, 2003)). French et al. (2006) in a review of eight studies which predicted attendance at cardiac rehabilitation interventions following acute myocardial infarction reported the constructs of identity (r=0.13) consequences (r=0.08), and cure/control (r=0.11)    to be positively significantly associated with attendance behaviour. In addition, Mc Sharry et al. (2011) located nine cross-sectional studies and four RCTs examining the relationship between illness constructs and the HbA1c, and found a similar result for identity (r=0.14) but higher effect size estimates for consequences (r=0.14). Other significant associations were found for timeline  orbitual (r=0.26), concern (r=0.21), and emotions (r=0.18). The most recent meta-analysis conducted by Hudson et al. (2014) included nine cross-sectional studies and found that individuals with high levels of constructs of timeline cyclical (r=0.25, depression r=0.31, anxiety), consequences (r=0.41, depression r=0.44, anxiety), and seriousness beliefs (r=0.38, depression) and lower perceptions of personal control (r=-0.27, depression r=-0.20, anxiety) are more likely to have poorer emotional health. Lastly, Hagger and Orbell (2003) review (N=45) addressed the validity of the model and the average co   rrelations of illness representation dimensions were significantly positive for identity-consequences (r=0.37, pComparison and contrasting of the modelsResearch focused on comparing and contrasting theories of health-related behaviour change assesses the utility of those theories to advancing understanding of behaviour change processes. The two theoretical models outlined above show a number of similarities and differences. Several observations can be made in comparing the similarities of the models. First, CSM-SR and TRA are both social cognitive models concerned with how cognitive determinants are influencing  for each one other in the regulation of behaviour and how these are applied to the understanding of health behaviours. Second, some constructs are common to both models, for example both CSM-SR and TRA are interested in how social-cognitive representations of health threat can motivate an individual to comply with his/her recommended treatment to avoid an adverse health outc   ome. Third, the models are used to analyse the influence of perceived factors external to individual on clinical-related behaviour. Moreover, both models explain behaviour change in terms of modifiable variables and support the importance of symptom attribution (Waller, 2006). Forth, CSM-SR and TRA are based on dynamic causal processes. In the CSM-SR, the individual regulates the interactions representations, coping mechanism and appraisal in an attempt to maintain coherence among them. In the TRA framework, changes in attitudes are influenced by changes in behavioural beliefs which ultimately produces changes in behaviour (Sutton, 2001). Lastly, both theories are used in developing intervention strategies, for example, related to help-seeking behaviour, by targeting modifiable variables (Waller, 2006).In contrasting the TRA and CSM-SR theoretical basis, the CSM-SR proposes that for a better understanding of individuals behavioural adherence, the researcher needs to  come across ref   erence to individuals attitudes toward the threatening condition. In contrast, TRA proposes that the motivation needs to be understood through individuals attitude toward the action of  going to the appointment/ treatment (Orbell et al., 2006). The CSM-SR emphasizes the importance of assessment of the likelihood of adherence through the evaluation of illness beliefs constructs (i.e. identity, timeline, cause, consequences, and cure/control), while in the TRA model only a single attitude is used to evaluate outcomes. Another distinctive contrast between the two models lies within the constructs of the framework. While the CSM-SR takes account of the impact of emotional variables, the TRA is  some entirely rational and does not account for emotional factors. Another aspect is that CSM-SR does not take account of the social influences that might shape illness beliefs or decision-making process, which is assessed by the TRA framework through subjective norms factor.The models also diffe   r in the way they are applied in research literature. The cognitive and emotional constructs of CSM-RS were designed specifically for understanding illness perception and adherence. (Leventhal et al., 1992). By contrast, TRA was designed to predict volitional behaviours, thus it can be applied to various behaviours, for example information technology (Mishra et al., 2014), software piracy (Aleassa et al., 2010), cyberbullying (Doane et al., 2014), hazing (Richardson et al., 2012), and domestic violence (Sulak et al., 2014).Looking at the differences in measuring the components of the models, CSM-SR uses a well-validated set of constructs developed by Weinman and colleagues (Weinman, Petrie, Moss-morris,  Horne, 1996). In contrast, the TRA models do not have a method per sei to measure its constructs. Thus, Ajzen  Fishbein (1980) provides an extensive details of the constructs for research to develop theory own measures.In conclusion, the TRA and CSM-SR are both social cognitive mode   l and their design is based on interpretation of cognitive factors in relation to behaviour change and each of them have their own weaknesses and strengths. Their  piece is significant and productive in the research literature because researchers can explore and test the theories to increases the understanding of health-related behaviours and help in the development of behaviour change interventions.
