Many learners report that they have been offered, sold or given illicit drugs at schools. Using dagga within school premises, or attending school after drinking alcohol or using data are also reported by many learners. In a bid to frame the interrelationships and intra-relationships of the multiple influences on drug and alcohol abuse behaviour, as well as how they operate at different levels, researchers and practitioners have identified two frameworks; the supply and demand framework and the Bronfenbrenner’s socio-ecological model (Bronfenbrenner, 1993). The Supply and Demand framework has three intervention windows: Demand side, Supply side and Harm Reduction (see Figure 11). On the demand side substance abuse is tackled through poverty reduction strategies, advocacy, education and communication, fostering socio-economic development and advancing anti-substance abuse social policies. On the supply side the key intervention areas include controlling production, sale, marketing and distribution of harmful substances. It also includes law enforcement and where necessary taking legal action against supplies of illegal substances. Harm reduction is based on treatment, aftercare and reintegration of those dependent on substances. The South African Drug prevention Master Plan employs the supply and demand framework.

Taking legal action on the use, abuse, production, Social Policy Application manufacture, marketing, distribution and trafficking of precursor materials, raw materials and products, refined drugs, manufacturing and distribution and facilities, and resources. The main drawback of the Supply and Demand framework is that it places intervention programmes in silos, with limited vertical and horizontal interactions. In reality, substance abuse is multifaceted challenge that requires a multidimensional and integrated set of intervention strategies. Figure 12 provides a pictorial view of the Bronfenbrenner socio-ecological framework. The framework implies that a substance abuser is affected by different types of environmental systems. The nested structures of these environmental systems begin with the individual domain, moving outwards to the microsystem, the mesosystem and finally, the exosystem. Applications of this framework can be found in Mason, Cheung, & Walker, (2004) for substance use; Yu, Stiffman, & Freedenthal, (2005) on tobacco use; and Marsden, Boys, 16 Farrell, Stillwell, Hutchings, et al. The ecological model takes a holistic view to the problem and demonstrates that factors driving drug abuse are interrelated and intervention strategies or programmes for combating the scourge should be integrated. The next paragraphs review literature on the determinants of substance abuse following the Bronfenbrenner’s socio-ecological model. Steinman and Zimmerman (2004) observe that behaviours such as low religious involvement, short-term goals in life, depressive symptoms and a poor sense of wellbeing and low self-esteem make the youth succumb to substance abuse. Evidence also points to the fact that youth are also prone to drug abuse because of their vulnerability (Mohasoa, 2010). Youth become vulnerable because they are in a phase of substantial experimentation, they are unemployed, have no income, and are poor, among other things (Kadalie & Thomas, 2013; Parry et al. Interviews with respondents, Rocha-Silva reported that youths use drugs 17 to gain confidence in dealing with people and stressful situations surrounding them. Mohasoa (2010) also reports that youth use substances because they are overwhelmed by the challenges in their own lives or families, and society at large. For example, stressors in their own lives could be cold weather which may lead them to taking solvents in order to escape the misery associated with the stressful environment. Microsystem The microsystem envelopes the individual domain and represents one’s immediate environment.
On the other hand generic super p-force oral jelly 160mg fast delivery erectile dysfunction queensland, if there were 0% cure and 100% death no one would ever take the pill unless the patient is extremely depressed and considers their life totally worthless super p-force oral jelly 160 mg sale erectile dysfunction related to prostate. Continue to change the cure-to-death ratio until the person cannot decide which course of action to take. Set up a “mini decision tree” and solve for the utility of living with chronic neurological deﬁcit. This is the value of living with a chronic stroke syndrome that the patient assigns as an outcome through a standard gamble. Different values will be obtained from each method used to measure patient values. The linear rating scale measures the quality of functionality of life, the time trade-off introduces a choice between two certainties, and the standard gamble introduces probability and willingness to take risks into the equation. Attitudes toward risk and framing effects Attitudes toward risk vary with individuals and at different periods of time during their lives. Patient values can be related to special events such as the birth of a Decision analysis and quantifying patient values 349 child or marriage, habits such as smoking or drinking, or age. The length of time involved in the trade-off will be different if asked of a younger or older person since a younger person may be less likely to be willing to trade off years. Also personal preferences related to the amount of risk a person is generally willing to take in other activities, such as sky-diving, play a role in determining patient values. Since values tend to be very personal, providers should not be the ones to assign these values. Values based on the provider’s own risk-taking behavior will not accurately measure the values of their patient. How the questions are worded or framed will inﬂuence the answer to the ques- tion. Asking what probability of death a patient is willing to accept will likely give a lower number than asking what probability of survival they are willing to accept. A patient is more likely to prefer a treatment if told that 90% of those treated are alive 5 years later than if told that 10% are dead after the same time period, even though the outcome is exactly the same. The feelings aroused by the idea of death are more likely to lead to the rejection of an option framed from the perspective of death when this same option would be endorsed in the opposite framing of the choice, the perspective of survival. Although apparently incon- sistent and irrational, this effect is a recurring phenomenon. This irrationality is not due to lack of knowledge since physicians respond no differently than non- physician patients. This is related to how individuals relate to numbers and how well people understand probabilities. In general, people (including physicians and other health-care providers) do not understand probabilities very well. Physicians tend to give qualitative rather than quantitative expressions of risk in many different and ambiguous ways. From the patient perspective, a rare event happens 100% of the time if it happens to them. Finally, patient values change when they have the disease in question as opposed to when they do not. Patients who are having a stroke are much more willing to accept moderate disability than well persons who are asked about the abstract notion of disability if they were to get a stroke. This means that stroke patients assign a higher value to the utility (U) of residual deﬁcit than well peo- ple asked in the abstract. Most clinical studies of these issues that are now being done have quality-of-life and patient-preference measures attached to possible outcomes. They should help clarify the effects of variations in patient values on the outcomes of decision trees. The health-care provider of the future will seek to use the most cost-efﬁcient methods to care for her or his patients. Cost-effectiveness analysis can be used to help choose between treat- ment options for an individual patient or for large populations. Governments and managed care organizations use cost-effectiveness techniques to justify their coverage for various health-care “products. Health-care providers, policy makers, and insurance- plan administrators must be able to evaluate the validity of these claims through the critical analysis of cost-effectiveness studies. If one treatment costs less and is clearly more effective than the alternative option, there is no question about which treatment to use.
