Intervention is rarely defined. It originates from the Latin inter between and venire to come and means coming between (Trevithick, 2005: 66). Interventions are at the heart of everyday social interactions and make inevitably make up a substantial majority of human behaviour and are made by those who desire and intend to influence some part of the world and the beings within it (Kennard et al. 1993:3). Social work interventions are purposeful actions we undertake as workers which are based on knowledge and understanding acquired, skills learnt and values adopted. Therefore, interventions are knowledge, skills, understanding and values in action. Intervention may focus on individuals, families, communities, or groups and be in different forms depending on their purpose and whether directive or non-directive.
Generally, interventions that are directive aim to purposefully change the course of events and can be highly influenced by agency policy and practice or by the practitioners perspective on how to move events forward. This may involve offering advice, providing information and suggestions about what to do, or how to behave and can be important and a professional requirement where immediate danger or risk is involved.
In non-directive interventions the worker does not attempt to decide for people, or to lead, guide or persuade them to accept his/her specific conclusions (Coulshed and Orme, 1998: 216). Work is done in a way to enable individuals to decide for themselves and involves helping people to problem solve or talk about their thoughts, feelings and the different courses of action they may take (Lishman, 1994). Counselling skills can be beneficial or important in this regard (Thompson 2000b).
Work with service users can therefore involve both directive and non-directive elements and both types have advantages and disadvantages (Mayo, 1994). Behaviourist, cognitive and psychosocial approaches tend to be directive but this depends on perspective adopted and the practitioners character. In contrast, community work is generally non-directive and person-centred.
Interventions have different time periods and levels of intensity which are dependent on several factors such as setting where the work is located, problem presented, individuals involved and agency policy and practice. Several practice approaches have a time limited factor such as task-centred work, crisis intervention and some behavioural approaches and are often preferred by agencies for this reason. In addition, practice approaches that are designed to be used for a considerable time such as psychosocial are often geared towards more planned short-term, time limited and focused work (Fanger 1995).
Although negotiation should take place with service users to ensure their needs and expectations are taken into account, it is not common practice for practitioners to offer choice on whether they would prefer a directive or non-directive approach or the practice approach adopted (Lishman, 1994). However, this lack of choice is now being recognised and addressed with the involvement of service users and others in the decision-making process in relation to agency policy, practice and service delivery (Barton, 2002; Croft and Beresford, 2000).
The purpose and use of different interventions is contentious. Payne (1996: 43) argues that the term intervention is oppressive as it indicates the moral and political authority of the social worker. This concern is also shared by others with Langan and Lee (1989:83) describing the potentially invasive nature of interventions and how they can be used to control others. Jones suggests that in relation to power differences and the attitude of social workers especially with regards to people living in poverty: the working class poor have been generally antagonistic toward social work intervention and have rejected social works downward gaze and highly interventionist and moralistic approach to their poverty and associated difficulties (Jones, 2002a: 12). It is recognised that intervention can be oppressive, delivered with no clear purpose or however, some seek and find interventions that are empathic, caring and non-judgemental due to practitioners demonstrating relevant experience and show appropriate knowledge (Lishman, 1994:14). For many practitioners, these attributes are essential in any intervention and are demonstrated through commitment, concern and respect for others which are qualities that are valued by service users (Cheetham et al. 1992; Wilson, 2000).
Dependent on the nature of help sought there are different opinions on whether interventions should be targeted on personal change or wider societal, environmental or political change. Some may want assistance in accessing a particular service or other forms of help and not embrace interventions that may take them in a particular direction i.e. social action (Payne et al. 2002). In contrast, problems may recur or become worse if no collective action is taken.
Importance has reduced in relation to methods of intervention over recent years as social work agencies have given more focus to assessment and immediate or short-term solutions (Howe, 1996; Lymbery 2001). This is strengthened by the reactive nature of service provision which is more concerned with practical results than with theories and principles. This has a reduced effect on workers knowledge of a range of methods resulting in workers using a preferred method which is not evidenced in their practice (Thompson, 2000). Methods of intervention should be the basis of ongoing intervention with service users, but often lacks structured planning and is reactive to crisis. This reactive response with emphasis on assessment frameworks is concerning, as workers are still managing high caseloads and if not supervised and supported appropriately, workers are at risk of stress and eventual burn-out (Jones, 2001; Charles and Butler, 2004).
Effective use of methods of intervention allows work to be planned, structured and prioritised depending on service users needs. Methods can be complicated as they are underpinned by a wide range of skills and influenced by the approach of the worker. Most methods tend to of application: assessment, planning of goals, implementation, termination, evaluation and review. Although the process of some methods is completed in three/four interactions others take longer. This difference shows how some methods place more or less importance on factors such as personality or society, which then informs the type of intervention required to resolve issues in the service users situation (Watson and West, 2006).
More than one method can be used in conjunction with another, depending on how comprehensive work with service users needs to be (Milner and OByrne, 1998). However, each method has different assessment and an implementation process which looks for different types of information about the service users situation for example, task centred looks for causes and solutions in the present situation and psychosocial explores past experiences. Additionally, the method of assessment may require that at least two assessments be undertaken: the first to explore the necessity of involvement and secondly, to negotiate the method of intervention with the service user.
An effective assessment framework that is flexible and has various options is beneficial but should not awkward or time consuming to either the worker or the service user. As Dalrymple and Burke (1995) suggest, a biography framework is an ideal way as it enables service users to locate present issues in the context of their life both past and present.
Workers should aim to practice in a way which is empowering and the process of information gathering should attempt to fit into the exchange model of assessment, irrespective of the method of intervention and should be the basis of a working relationship which moves towards partnership (Watson and West, 2006). As part of the engagement and assessment process, the worker needs to negotiate with the service user to understand the issue(s) that need to be addressed and method(s) employed and take into account not only the nature of the problem but also the urgency and potential consequences of not intervening (Doel and Marsh, 1992).
Importance should be placed on presenting and underlying issues early in the assessment process as it enables the worker to look at an assessment framework and approach that assists short or long-term methods of intervention. An inclusive and holistic assessment enables the service user to have a direct influence on the method of intervention selected and be at the heart of the process. The process of assessment must be shared with and understood by the service user for any method of intervention to be successful (Watson and West, 2006).
The workers approach also has an influence on method selection as this will affect how they perceive and adapt to specific situations. The implementation of methods is affected by both the values of the method and value base of the individual worker. The worker will also influence how the method is applied in practice through implementation, evaluation, perceived expertise and attitude to empowerment and partnership.
Methods such as task centred are seen to be empowering with ethnic minority and other oppressed groups as service users are seen to be able to define their own problems (Ahmad, 1990). However, when an approach is used which is worker or agency focused the service user may not be fully enabled to define the problem and results in informing but not engaging them in determining priorities.
Empowerment and partnership involves sharing and involving service users in method selection, application of the method, allocation of tasks, responsibilities, evaluation and review and is crucial in enabling facing challenges in their situations and lives. However, service users can have difficulty with this level of information-sharing and may prefer that the worker take the lead role rather than negotiating something different and not wish to acquire new skills to have full advantage of the partnership offered.
