Further 10mg aricept sale, Palmentera (1996) stated that reactant individuals demonstrated more stress buy 5 mg aricept mastercard, hostility order 10mg aricept free shipping, and emotion-focused coping styles with feelings of self-deprecation linked to depressive symptoms. Thus, the psychological ramifications of highly reactant behaviors may hinder therapeutic relationships with health care providers (Seemann, Buboltz, Jenkins, Soper, & Woller, 2004) and impede adherence to the treatment regimen, especially medication-taking (Christensen, 2004). Blacks had higher levels of reactance than Whites on the verbal, behavioral, and total therapeutic reactance scale. Woller, Buboltz, and Lovelace (2007) further stated that differences in reactance levels for minority groups may result from disparate environmental opportunities related to discrimination that restricts free behavior, especially for Blacks and Hispanic/Latinos. Thus, reactance behaviors experienced in society may be generalized to relationships with health care providers implementing the treatment regimen. The vast amount of literature on lack of compliance and adherence attest to the continual resistance of individuals to taking medications, even though they may receive pertinent information, interventional strategies, and admonishments (Fogarty, 1997; Pound et al. Several authors contend that because varying degrees of resistance exist and are usually hidden from health care providers, it is highly unlikely that individuals will stop resisting prescribed medications (Fogarty, 1997; Pound et al. Intrinsic motivation as described by Cox and Brehm‘s reactance theory may provide insight into factors that promote adherence behaviors. The rationale for reactant behaviors and resulting resistance to the treatment regimen, particularly medication- taking, warrants further exploration. Cognitive appraisal provides insight into the client‘s perceptions and interpretation of his or her health status, behavioral choices, and interaction with the health care provider (Cox, 1982). Importantly, the client‘s perceptions and interpretations are representative of his or her reality and may or may not reflect that of the health care professional (Carter & Kulbok, 1995; Cox, 1982). While educational information is usually beneficial for individuals who are motivated to adhere to the treatment regimen but unlearned in regimen process, individuals unmotivated in adherence and already knowledgeable are unlikely to improve with additional educational information (Becker, 1985). Thus, client education is essential, although its effectiveness may be questioned, especially when intrinsic motivation is lacking. Becker (1985) asserts that providing information to clients about diagnosed illnesses and prescribed treatments have not increased adherence. However, literacy was not reported as an issue in this study even though over 45% of the sample had less than a high school education. Literacy issues may be one of the primary reasons for uncertainty of educational effectiveness. Low literacy levels can result in difficulty understanding health information, accessing health care, following instructions from a health care provider, and taking medications correctly; all of which 62 contribute to poor adherence to the treatment regimen, uncontrolled chronic disease, and increased health care costs (Safeer & Keenan, 2005). Milio (1976) exerts is that it is not enough to make clients knowledgeable about healthy lifestyle choices without assuring that clients have ready access to the treatment options promoted. If health care providers adequately assess clients prior to implementing treatment and allow clients an opportunity to exert control over determining optimal health for themselves, then the actions necessary to attain their health status could be implemented according to the client‘s environmental limitations (Carter & Kulbok, 1995; Cox, 1982). Adequate assessment of the client‘s ability to practice positive health behaviors within the environmental resources available may provide a realistic expectation for the client to succeed in adhering to the health care regimen and allow the health care provider an opportunity to individualize the health care regimen, thus making adherence a viable possibility. As defined by Riegel, Lee, Dickson, and Carlson (2009), self- care is a decision-making process that clients naturally use to choose behaviors to maintain their physiological status and manage any symptoms that may occur. Maintenance refers to living a healthy lifestyle, adhering to the treatment regimen, and monitoring symptoms that may require decision making if a response is needed. Conversely, management is the deliberate process of action to recognize symptoms, evaluate the need to act, implement a treatment strategy, and evaluate treatment effectiveness (Riegel et al. Thus, clients are left to self-manage symptoms that arise and engage in decision-making and problem-solving to maintain their physiological status (Pascucci et al. Therefore, clients who are expertly engaged in self-care should possess qualities such as knowledge, experience, and skill relevant to their disease process (Riegel et al. Evidence has shown that education alone is not effective in improving client adherence to antihypertensive medications. However, dietary advice has shown modest short-term improvements in fat intake and fruit and vegetable consumption. Conversely, advice to increase physical activity has not shown effectiveness (Viera & Jamieson, 2007). The system was designed to initiate alerts if the client does not complete scheduled self-testing, did not take medications as prescribed, or exceeded specified clinical parameter thresholds. A nurse monitored the system, contacted clients to counsel and educate and notified the physician of client events monthly and problem areas as needed. Client trust is an essential element of the client and health care provider relationship that directly impacts adherence to the treatment regimen (P. According to Cox (2003), the content of the health care provider‘s interaction and sensitivity to the client‘s elements of singularity are evidenced by the client‘s satisfaction with care, which is strongly predictive of subsequent adherent behavior. However, trust with 65 Black clients differs from White clients because Blacks generally consider health care providers as untrustworthy. Therefore, signals of distrust by Blacks may include behaviors such as anger (Watkins & Terrell, 1988), assertive behaviors that are oftentimes misinterpreted as attitudinal or militant (Fongwa, 2002), and request for the services of a Black health care provider (Flack et al. Lack of trust in health care providers hinders the establishment of a trusting client-health care provider relationship. Factors that may impede relationship development include health care disparities (Greer, 2010; L. Lewis & Ogedegbe, 2008), multiple episodes of real and perceived racism or discrimination (Greer, 2010), and lack of health care provider cultural competency (Flack et al.
