A model is a simplified representation of the structure and content of a phenomenon or system that describes or explains the complex relationships between concepts within the system and integrates elements of theory and practice (Creek et al 1993).A nursing model is a body of ideas and knowledge that represents nursing from the authors' point of view, presenting different ways of seeing and understanding nursing ( Aggleton and Chalmers, 2000; Hogston and Simpson, 2002). Thus, the nursing model is a concept of what nursing is and is used as a tool to assess patient needs/problems. The nursing model differentiates nursing from other disciplines and activities in that it serves to describe, explain, predict and control the desired outcomes of nursing practices. Models can be tested, modified, or used to guide research or provide a basis for evaluation (Blais, 2002). There are many models available, including Roper Logan Tierney (RLT) (1996). The RLT model, which my portfolio based, provides a framework for nurses to ensure that individuality is taken into account when considering nursing care. To ensure that all aspects of an individual's life are integrated into an effective care plan, Roper et al (1996) use a problem-solving approach and the nursing process in conjunction with their nursing model. The RLT model is holistic, as it identifies five components, including activities of daily living (ADL), lifespan, dependence/independence, factors influencing AL and individuality in life, which are interrelated (Healy and Timmins, 2003; Holland et al, 2004; Roper et al, 1996). Roper et al (2000) view the patient as a life-long individual, with changing levels of dependence and independence depending on age, circumstances and environment (Healy and Timmins, 2003). The twelve ADLs are influenced by five factors, namely: biological, psychological, sociocultural, environmental and political-economic (Healy & Timmins, 2003; Holland et al, 2004; Roper et al, 1996). The RLT model individualizes care using the nursing process. The model guides the nursing process, as it directs the nurse to assess ADLs (Holland et al, 2003; Roper et al, 2000; Tierney, 1998). Nursing care models are flexible and can be modified to provide individualized care, meaning that the needs of an individual patient are met at any given time (Radwin & Alster, 2002). However, this is not always achieved in practice (Waters & Easton, 1999).
