Assertiveness and Anxiety: Saying What You Need Without the Guilt

You want to say no, but you say yes. You disagree, but you nod along. Someone crosses a boundary and you swallow the discomfort rather than name it. Later, you feel frustrated — with the other person and with yourself. This lesson looks at why speaking up is especially hard when you’re anxious, and how to build the skill.

Learning objective

By the end of this lesson, you should be able to distinguish assertive, passive and aggressive communication, explain why anxiety promotes passivity, and try one assertive script.

The concept

Three styles of communication

Assertiveness researchers have long described three broad styles [3] [6]:

Style	What it sounds like	What it protects
Passive	“It’s fine, whatever you want.”	Other person’s comfort, at your expense
Aggressive	“I don’t care what you think, we’re doing it my way.”	Your needs, at the other person’s expense
Assertive	“I understand your point. Here’s what I need.”	Both people’s needs and dignity

Most people use all three at different times. The question is whether you have access to the assertive option when you need it, or whether anxiety pushes you toward passivity by default.

Why anxiety promotes passivity

Anxiety is fundamentally about threat prediction. In social situations, the predicted threats are often interpersonal: anger, rejection, disapproval, conflict. Passive communication avoids all of these — at least in the short term.

The anxious reasoning goes:

• “If I say no, they’ll be upset with me” → stay quiet.
• “If I disagree, they’ll think I’m difficult” → agree.
• “If I set a boundary, they’ll leave” → accommodate.

Each time passivity prevents the feared reaction, the belief that speaking up is dangerous is reinforced. This is the same avoidance mechanism described in an earlier lesson, applied to communication rather than situations.

What the evidence shows

Assertiveness training was one of the earliest behavioral interventions and has been studied since the 1970s. Speed, Goldstein and Goldfried reviewed the evidence and argued that assertiveness training is an overlooked but effective treatment component, particularly for anxiety and depression [1].

A systematic review by Lin and colleagues examined the effectiveness of assertiveness training specifically for anxiety and found that programs incorporating role-play, modeling and homework produced consistent reductions in anxiety symptoms [5]. CBT for social anxiety frequently includes assertiveness work as a core component [4].

A worked example

The following is a fictional example used for teaching.

Dani’s manager asks her to take on a third project. She already feels overwhelmed by the first two and knows she cannot do justice to another one. Her chest tightens.

Passive response: “Sure, I can probably manage that.” (She doesn’t manage it. Quality drops on all three. She blames herself.)

Aggressive response: “You can’t be serious. I’m already drowning and nobody seems to notice.” (The manager becomes defensive. The relationship suffers.)

Assertive response: “I appreciate being asked. I’m currently working on [Project A] and [Project B], and I want to do both well. If I take on a third, something will slip. Could we talk about priorities?”

The assertive response names the reality, respects the manager’s position, and opens a conversation rather than issuing a verdict. Dani may still feel anxious saying it — assertiveness doesn’t eliminate anxiety. But the outcome is more sustainable than either passivity or aggression.

A common misunderstanding

“Assertive people are naturally confident.” Many assertive people feel anxious before and during the conversation. Assertiveness is a skill, not a personality trait. It can be awkward, uncomfortable and imperfect, and it still counts.

Exercises to try

1. The assertive formula

When you need to set a boundary or express a need, use this three-part structure:

1. Acknowledge: “I understand that you need this done quickly.”
2. State your position: “I’m not able to take it on this week.”
3. Offer an alternative (if appropriate): “Could we look at next week, or is there someone else who could help?”

Write out the three parts before the conversation if you need to. Having the words prepared reduces the cognitive load in the moment.

2. Start small

Assertiveness is a graduated skill. Start with low-stakes situations:

• Send back a dish that isn’t what you ordered.
• Tell a friend you’d prefer a different restaurant.
• Say “I need a minute to think about that” instead of answering immediately.

Each successful attempt provides evidence that the feared reaction (anger, rejection) usually doesn’t happen, or is manageable when it does.

3. The broken-record technique

If someone pushes back on your boundary, calmly repeat your position without escalating or backing down:

• “I understand. I’m still not able to take it on this week.”
• “I hear you. My answer is the same.”

Repetition without aggression is one of the hardest assertiveness skills, and one of the most effective.

When to talk to a professional. Speak to a GP or mental health professional if difficulty speaking up is causing significant problems in your relationships, work or self-esteem, or if the anxiety behind it is persistent and distressing. CBT and assertiveness training can help. If you’re in crisis, call or text 988 (US) or contact Samaritans on 116 123 (UK and Ireland).

Recap

• Assertiveness means expressing your needs clearly and respectfully.
• Anxiety promotes passivity by predicting negative social consequences.
• Assertiveness is a learnable skill, not an innate trait.
• Starting with low-stakes situations builds confidence and evidence.
