Depression is a complex condition that confuses whether one's feelings are just sadness or something more. It can result from various factors, including genetics, life stressors, and brain chemistry. Self-assessment tools can help identify symptoms, but professional evaluation and support are essential for accurate diagnosis.
"You know how kids these days are all depressed, it's become part of Gen Z lingo," K's mother sighed, her voice heavy with judgment as she sorted laundry. K had been quiet, withdrawn, and seemingly lost in her world.
K lost in the glow of her phone, searched for answers to the persistent low mood clouding her days. She ignored her mother's dismissive comments about depression being a problem for "rich adults," struggling to understand her feelings.
A single thought echoed in her mind: “Am I depressed or just sad?”
What is Depression?
Depression, a common mental health condition, can significantly impact a person's thoughts, emotions, and behaviours. In 2019, an estimated 280 million people worldwide suffered from depression, and this number is likely to continue rising. Contrary to the belief that depression is a trend or a fad, it can affect anyone, regardless of age, gender, or socioeconomic status. It has a significant impact on both the emotional and physical health of the individual – impacting not just their image of themselves but also their perception of their interpersonal relationships.
Causes of Depression
While depression can be influenced by various factors, some common causes include:
- Genetics: A family history of depression can increase an individual's risk.
- Brain Chemistry: Imbalances in neurotransmitters, such as serotonin and dopamine, can contribute to depressive symptoms.
- Medical Conditions: Certain medical conditions, like thyroid disorders or chronic pain, can trigger depression.
- Stressful Life Events: Significant life changes, such as job loss, relationship breakups, or the death of a loved one, can lead to depression.
Signs of Depression
Like K, many people struggle to understand their own experiences with depression due to societal stigma. According to the ICD-10, some of the common symptoms of a depressive episode can include:
- Reduced concentration and attention
- Reduced self-esteem and self-confidence
- Ideas of guilt and unworthiness
- Bleak and pessimistic views of the future
- Ideas or acts of self-harm or suicide
- Disturbed sleep
- Diminished appetite
The process of recognising and understanding the symptoms of an illness can be isolating, often exacerbating emotional distress. As K grapples with her feelings of depression, she finds herself defending her mother's ignorance, even though her primary concern is her self-understanding.

Imagine if K had a ‘depression screening test’ so to speak that could identify potential signs of depression. But you don’t need to imagine as there are self-assessment tools that are designed to help you and clinicians examine your depression.
By using these tools, K could screen herself and determine whether further evaluation by a mental health professional is necessary. Early identification and intervention are crucial for preventing the worsening of depressive symptoms. These self-assessment tools often involve rating the frequency or intensity of various symptoms. Some of these tools are:
Patient Health Questionnaire
PHQ-9 is a widely used self-assessment tool designed to measure the frequency of depressive symptoms over the past two weeks. It is used by people in general and healthcare professionals worldwide and can be used to track symptom progression over time.
Beck Depression Inventory
BDI is a widely used self-report tool that assesses the severity of depression. This depression quiz, so to speak. consists of 21 questions related to symptoms such as sadness, hopelessness, guilt, and physical symptoms like sleep disturbances and appetite changes. Individuals rate the intensity of these symptoms on a scale of 0 to 3, with higher scores indicating more severe depression. Suitable for individuals aged 13 to 80, the BDI is a reliable and accurate tool for screening and measuring depression.
Quick Inventory of Depressive Symptomatology-Self-Report
QIDS-SR is a tool used to assess the severity of depression in adults aged 18 and older. Respondents rate their symptoms on a 4-point Likert scale, taking approximately 5-7 minutes to complete.
The WHO Depression Self-Assessment Tool
This tool is designed to help individuals assess their depressive symptoms. It asks questions about past diagnoses, treatments, and specific symptoms like sadness, loss of interest, and sleep disturbances. Based on the responses, the tool provides a score to estimate the severity of depression. This simple tool can help individuals reflect on their mental health and seek appropriate support.
The Zung Self-Rating Depression Scale
SDS is a tool used to measure the severity of depressive symptoms. It consists of 20 items, each rated on a scale of 1 to 4. A higher total score indicates more severe depression. The SDS assesses various aspects of depression, including emotional, psychological, and physical symptoms.
Hamilton Rating Scale for Depression
HAM-D is a tool used by mental health professionals to assess the severity of depression symptoms in adults. It covers various symptoms, including mood, guilt, anxiety, and sleep disturbances. The HAM-D helps clinicians diagnose depression, plan treatment, and monitor treatment progress.
Taking Care of Yourself: Beyond Self-Assessment
As K delves deeper into her understanding of depression, it's crucial to explore practical steps for self-care and seeking professional help.
- Consultation with a Mental Health Professional: Consulting a mental health professional, such as a psychiatrist or clinical psychologist, can provide valuable insights into the nature and severity of depressive symptoms. They can offer a comprehensive diagnosis and tailor a treatment plan to K's specific needs.
- Treatment Options: The treatment plan may involve a combination of pharmacological and therapeutic interventions. A mental health professional can educate K about various treatment options and help her make informed decisions.
- Prioritising Self-Care: Engaging in self-care activities can significantly improve mental well-being. Simple practices like maintaining a healthy diet, establishing a regular routine, and incorporating physical exercise, such as yoga or daily walks, can have a positive impact.
- Building Strong Social Connections: Social support plays a vital role in mental health. Connecting with loved ones and friends, or joining support groups can provide a sense of belonging and reduce feelings of isolation.
The journey of self-discovery can be emotionally taxing, and seeking support from others can make a significant difference.
Conclusion
It's understandable that withdrawing from social interactions and lacking emotional support can exacerbate depressive symptoms. That's why support groups are so valuable. They provide a safe space for individuals like K to connect with others who share similar experiences and offer mutual understanding and support.
If you or someone you know is struggling with depression, consider using self-assessment tools to screen for symptoms. Don't hesitate to reach out to a mental health professional. Remember, you're not alone in this journey.
