Psychological Explanation of Clinical Depression

Welcome to the Psychological Explanation of Depression!

In this section, we are going to look at how our thoughts can influence how we feel. While some people look at biology (like genes or brain chemicals) to explain depression, psychological explanations focus on our mind and our patterns of thinking. Don't worry if this seems a bit deep at first—we'll break it down into simple steps!

Quick Review: What is Clinical Depression?
Before we dive in, remember that clinical depression is a mental health problem where a person feels very low for a long time, loses interest in things they used to enjoy, and has very little energy. It is much more than just "feeling a bit sad."

The Main Theory: Ellis’s ABC Model

Psychologist Albert Ellis believed that people with depression have a different way of looking at the world. He suggested that it isn't the bad things that happen to us that make us depressed, but rather how we think about those things. He called this the ABC Model.

1. Activating Event (A)

The "A" stands for an Activating Event. This is something that happens in the outside world. It could be something big, like failing an exam, or something small, like a friend not replying to a text message immediately.

2. Beliefs (B)

The "B" stands for Beliefs. This is how you interpret the event. This is the most important part! Ellis said there are two types of beliefs:
- Rational Beliefs: These are healthy and realistic. Example: "I'm sad I failed the test, but I can study harder next time."
- Irrational Beliefs: These are unhealthy and unrealistic. Example: "I failed the test because I am completely stupid and I will never succeed at anything."

3. Consequences (C)

The "C" stands for Consequences. This is the result of your belief. If you have irrational beliefs, the consequence is likely to be clinical depression or extreme anxiety. If your beliefs are rational, you might feel sad, but you stay healthy.

Did you know?
Ellis used a term called "musturbatory thinking." This is the habit of thinking that things MUST be a certain way (e.g., "I must be loved by everyone"). When these "musts" aren't met, it leads to irrational beliefs!

Key Takeaway: It’s not the event (A) that causes depression (C); it’s the way we think about it (B) that makes the difference!

Understanding Rational vs. Irrational Beliefs

Think of your beliefs like a pair of glasses.
- Rational beliefs are like wearing clear glasses—you see the world as it really is.
- Irrational beliefs are like wearing dark, distorted glasses—everything looks much worse than it actually is.

Real-World Example:
Imagine you walk past a friend in the hallway and they don't say hello.
Rational Thought: "They probably didn't see me or they are having a busy day." (Consequence: You feel fine).
Irrational Thought: "They are ignoring me because they hate me and I have no real friends." (Consequence: You feel depressed and lonely).

The Core Study: Tandoc et al. (2015)

To support this idea that our thinking causes depression, we look at a study by Tandoc et al. about Facebook use.
They found that Facebook itself doesn't cause depression. Instead, it only leads to depression when it causes envy.
When people look at others' "perfect" lives and think, "My life is terrible compared to theirs," they are using irrational beliefs and social comparison. This supports the idea that our interpretation of what we see is what affects our mental health.

Quick Review Box: The ABC Process
1. Activating Event: Something happens.
2. Belief: You tell yourself a story about why it happened.
3. Consequence: You feel an emotion based on that story.

Evaluating the Theory: The Great Debate

In Psychology, we always look at the strengths and weaknesses of a theory. For the ABC Model, we look at the Freewill vs. Determinism debate.

Is it Freewill?
This theory suggests we have freewill because it says we can choose how we think. If we can change our irrational thoughts into rational ones, we can "cure" our depression. This is the basis for therapies like CBT (Cognitive Behavioural Therapy).

Is it a Weakness?
Some people argue this theory is deterministic in a bad way—it almost "blames" the person for being depressed because of their "wrong" thinking. It might ignore biological factors (like low serotonin) or real-life problems (like poverty or abuse) that the person cannot control.

Common Mistake to Avoid:
Don't say that the "Activating Event" causes depression. In an exam, you must emphasize that the Belief (B) is the link that leads to the Consequence (C).

Summary of Psychological Explanations

Key Takeaway 1: Depression is caused by irrational thinking and irrational beliefs.
Key Takeaway 2: The ABC Model explains the process: Activating Event -> Belief -> Consequence.
Key Takeaway 3: This theory is helpful because it gives people power (freewill) to change their thoughts, but it may ignore biological causes of depression.

Great job getting through these notes! Clinical depression is a complex topic, but remembering the "ABC" steps will help you stay on track for your exam. Keep going!
