Psychological profiling and designing personalized interventions for the management of distress in cancer patients is one of the new approaches in psycho-oncology that is based on the principle that the psychological experience of cancer is not the same for all patients and that a similar intervention program cannot be considered for all people with cancer. Cancer can be associated with anxiety and fear of the future for one patient, depression and feelings of helplessness for another, for one person with sleep disturbances and fatigue, and for another disease with family problems, economic concerns, body image changes, or fear of recurrence. Therefore, accurate recognition of the psychological pattern of each patient and identification of the factors that cause and sustain distress can provide the ground for choosing an intervention tailored to individual needs. In this approach, the purpose of profiling is not merely to determine the severity of distress, but to draw a multidimensional picture of the patient's emotional, cognitive, behavioral, social, and even semantic state so that the path of psychological care can be personalized based on it.
Distress in psycho-oncology is a multidimensional concept that can include anxiety, depression, worry about the future, fear of relapse, sleep disturbances, communication problems, economic difficulties, occupational and family problems, and other stresses caused by illness and treatment. For this reason, an overall Distress score alone cannot determine why a patient is distressed or what type of intervention is best suited for them. They may have screening tools, but the factors causing their distress are quite different. One may have been distressed due to fear of relapse and the other may have been distressed due to pain, financial difficulties, or family conflict. Psychological profiling attempts to uncover these differences and move the assessment from a general assessment to an understanding of the structure and pattern of distress of the individual.
In designing a comprehensive psychological profile, it is necessary to examine several areas. Demographic and medical characteristics such as age, type of cancer, stage of disease, treatment history, and physical status, along with psychological variables such as anxiety, depression, emotion regulation, coping styles, intolerance of uncertainty, self-efficacy, and resilience can also provide important information. Also, sleep quality, fatigue intensity, pain, body image, sexual function, quality of family relationships, social support, economic status, and occupational concerns should be considered when they are related to the patient's experience.
One of the fundamental principles of personalisation of interventions is that the severity of the problem is matched with the type of intervention. Not all patients require intensive psychotherapy, and in contrast, for a patient with severe distress, general education and short-term support may not be enough. The phased care model can be applied in this context, in which patients with mild distress benefit from psychological education, self-care and periodic monitoring, patients with moderate distress receive short-term targeted interventions, and those with severe, persistent, or complex symptoms are referred for more specialized assessment and treatment. Such a model makes more rational use of psychological resources and increases the relevance of the intervention to the patient's needs.
Profiling can also be done based on the underlying mechanisms of distress . In a patient where the dominant pattern is worry and intolerance of uncertainty, the intervention can focus on worry management, cognitive restructuring, acceptance of uncertainty, and reduction of catastrophic predictions. If the dominant pattern of depression is withdrawal and activity reduction, behavioral activation, a gradual return to meaningful activities, and strengthening social connections can become more important. In patients with emotion regulation problems, emotion recognition training, acceptance of difficult emotions, cognitive reappraisal, and distress tolerance can be the main focus of the program. Therefore, personalization does not mean changing the mere number of sessions, but rather changing the content of the intervention based on the main mechanism of the problem.
In the field of psycho-oncology, attention to the stage of the disease is also of particular importance. The psychological needs of the patient at the time of the initial diagnosis are not the same as the period of active treatment or the period after the end of treatment. During the diagnosis, shock, fear, and difficulty in accepting the reality of the disease may become more prominent. During treatment, physical complications, fatigue, sleep disturbances, worry about responding to treatment, and changing family roles become more important. After the end of treatment, fear of relapse, return to normal life, change of identity, and worry about the future may become the main focus of Distress . Therefore, the psychological profile should be dynamic and reviewed along the course of the disease.
Research evidence in the field of psycho-oncology supports the view that psychological interventions can reduce the distress and emotional problems of patients with cancer, but the response rate varies from person to person. This difference in response has increased the importance of moving from a "one-size-fits-all" approach to personalised care. Individual factors, the severity of symptoms, the type of cancer, social support, the quality of the treatment relationship, the patient's willingness to change, and medical conditions can affect the effectiveness of the intervention. Therefore, personalization should continue not only before treatment begins, but also throughout the treatment process.
One of the important applications of profiling is to establish a link between assessment and treatment decision-making. Psychological evaluation acquires real clinical value when the outcome leads to a specific decision. For example, identifying an intense fear of relapse should be able to activate the pathway to receive an intervention related to fear management and uncertainty. The diagnosis of a sleep disorder should be accompanied by an examination of physical, pharmacological and psychological factors and the selection of the appropriate intervention. Identifying low social support can also call for activation of a support network or referral to social work services. As a result, psychological profiling should be transformed into a blueprint for intervention, rather than simply a set of scores left in the patient's record.
The relationship between physical and psychological factors should also be considered in the design of the profile. Pain, nausea, fatigue, sleep disturbances, and changes in appetite can be both a consequence of treatment and an exacerbating factor of distress . On the other hand, anxiety and depression can also affect the perception of physical symptoms and quality of life. For this reason, a complete separation of body and mind does not make sense in the evaluation of a patient with cancer. A personalized approach should be carried out in collaboration with the medical and psychological team to determine which part of the problem needs medical intervention, which part needs psychological intervention, and which part needs social support or a combination of them.
Digital technologies and data analytics could also play an important role in psychological profiling in the future. Electronic health records, digital screening tools, mood monitoring apps, and data from wearable devices can provide longitudinal information about a patient's sleep, activity, fatigue, and emotional changes. Combining this data with clinical evaluation can allow for the creation of more dynamic profiles. However, digital data should not replace human dialogue and expert judgment, as many aspects of the cancer experience, such as meaning, fear, family relationships, and a sense of security, can only be properly understood through direct communication with the patient.
From a therapeutic perspective, personalization can include the choice of approach, intensity, number of sessions, and method of delivery of the intervention. For some patients, structured cognitive-behavioral intervention is appropriate; for others, a supportive approach, mindfulness, acceptance and commitment-based therapy, meaningful interventions, or coping skills training may be more appropriate. Some patients may also respond better to face-to-face interventions and some to online or telephone sessions. Physical conditions, geographic distance, treatment plan, and patient preference should also be involved in this choice. This flexibility can increase patient engagement and reduce the likelihood of dropping treatment.
One of the main challenges of this approach is the excessive complexity of the assessment process. If profiling is accompanied by a large number of questionnaires and lengthy assessments, it may be tedious for a patient undergoing cancer treatment. Therefore, it is necessary to strike a balance between comprehensiveness and the burden of assessment. The use of short, valid tools and the selection of variables based on clinical need can reduce this problem. Assessment should also be iterative but targeted, and not all variables should be re-evaluated at each session.
Another limitation is the risk of labeling and reducing the patient's complex experience to a single "profile". The psychological profile should be a decision-support tool and not a fixed psychological identity of the patient. A person may have high anxiety at one stage of the illness and experience a completely different situation a few months later. Therefore, the profile should be dynamic and revisible. The patient should also know that the results of the assessment are used to support him and not to judge or exclude him from certain health services.
In the design of personalised interventions, the patient's own involvement is also of fundamental importance. The patient should be involved in setting treatment goals and the intervention should be tailored to his or her real-life priorities. For one person, returning to work may be the main goal, for another it may be to maintain contact with the family, and for another to reduce the fear of relapse or improved sleep. If treatment goals are set solely by the specialist, the program is likely to diverge from the patient's actual needs. The patient's active participation can increase the patient's sense of control, self-efficacy, and motivation.
To develop this approach, future research should move towards longitudinal and multidimensional models, investigating which features of psychological profiles can predict responses to specific interventions. The use of machine learning methods and longitudinal data analysis can also make it possible to identify hidden patterns of vulnerability and response to treatment, but these technologies must be accompanied by rigorous validation and expert monitoring. Studies should also include diverse patient populations, different types of cancer, and different stages of the disease so that personalised models can be more generalizable.
Psychological profiling in psycho-oncology can provide a bridge between general screening and specific intervention. Rather than considering distress as a fixed and uniform score, this approach attempts to identify the structure, severity, causative factors, and psychological needs of each patient, and then design an intervention tailored to individual characteristics, stage of disease, and life circumstances based on this information. Such an approach can avoid providing unnecessary interventions to some patients and underpaying attention to patients with complex needs. Ultimately, the goal of personalization in psycho-oncology is not to create a completely different and separate program for each patient, but rather to create a flexible system that can choose the most appropriate level and type of support based on the patient's actual profile, distress intensity, coping resources, risk factors, and preferences. Moving toward such models can shift psychological cancer care from a generic and reactive approach to more rigorous, preventive, dynamic, and patient-centered care.
